Reese has designed towing equipment since 1952 and remains a benchmark for heavy-duty towing. The line covers fifth wheel hitches such as the modular M5, gooseneck couplers including the Goose Box, air-ride and short-bed pin boxes, weight distribution systems with active sway control, and the accessories that connect them, all built to exceed published industry standards.
Reese has been pioneering towing performance since 1952, when Margaret Reese asked her husband TJ to stop travel trailers rocking every time somebody walked through them. His answer, the first pair of stabilising jacks, was simple and effective enough to change the RV industry. From that starting point Reese grew into a designer and manufacturer of complete towing systems, and today it anchors the heavy-duty end of the Horizon Global towing portfolio.
Fifth wheel towing is where the brand's engineering is most visible. The M5 fifth wheel hitch uses a modular design that breaks into manageable sections for assembly, with a wider stance, tighter tolerances and a shock absorption system aimed at the jolts that travel up through a truck bed. For owners who would rather tow from a gooseneck coupler and keep the bed clear, the Goose Box 20K replaces the trailer's king pin with a gooseneck connection carrying its own air-ride cushioning.
Pin boxes are a Reese speciality. The 5th Airborne uses air-ride technology to dampen road shock and reduce the chucking motion that makes fifth wheel towing tiring, while the Sidewinder was designed for short-bed pickups, pivoting the connection point so the trailer can turn sharply without the front cap meeting the cab.
For conventional towing, Reese weight distribution systems restore load to the tow vehicle's front axle and control sway. The Pro Round Bar distributes weight evenly while damping sway, and the Pro Dual Cam II uses active cam-based sway control that works harder the stronger the sway force becomes. Complete kits pair bars, head and shank to a rated tongue weight, and dedicated sway control kits can be added to existing setups. The products suit RV owners, horse and livestock haulers and anyone towing near the upper end of a vehicle's rating.

The Goosebox is a gooseneck trailer hitch coupler that mounts to a pickup truck bed and couples with a 2 5/16" diameter gooseneck ball on a trailer. It allows the truck to tow a gooseneck trailer. Two models are available: the 94920 (20,000 lbs gross trailer weight rating, 4,000 lbs max pin weight) and the 94980 (22,500 lbs gross trailer weight rating, 4,000 lbs max pin weight). The Goosebox includes an air suspension system that can be adjusted for ride comfort.
The Goosebox is designed to work only with a 2 5/16" diameter gooseneck ball. The ball must be locked within the housing of the truck bed.
The manual provides installation examples for Lippert 1621 (2 mounting positions providing 2 inches of adjustment), Lippert 1716 (2 mounting positions providing 2.5 inches of adjustment), and Lippert Rhino (1 mounting position with a maximum load of 20,000 lbs). For other wing sets, contact Technical Service at 1-800-632-3290 or visit https://qr.towingproducts.net.
The 94920 Goosebox has a maximum gross trailer weight rating of 20,000 lbs. This is the combined weight of the trailer and all its contents. The gross trailer weight must not exceed the lowest rating of the truck, hitch, and trailer.
The 94980 Goosebox has a maximum gross trailer weight rating of 22,500 lbs. This is the combined weight of the trailer and all its contents. The gross trailer weight must not exceed the lowest rating of the truck, hitch, and trailer.
The maximum pin weight is 4,000 lbs for both the 94920 and 94980 models. Pin weight is the downward force exerted on the gooseneck ball by the Goosebox and its load. The Goosebox is designed for a maximum of 20% of the gross trailer weight on the gooseneck ball.
A minimum clearance of 2 feet between the bumper and trailer (measured at the same height) is recommended. If clearance is less than 2 feet, test the clearance after installation by making a slow turn in a controlled environment such as a closed parking lot or grass field with an observer watching for interference.
Approximately 7 inches of clearance should be maintained between the top of the truck bed sides and the underside of the front of the trailer to allow for pitch and yaw of the trailer during towing. For off-road use, allow more clearance. The Goosebox height is adjusted via the air suspension system to achieve this clearance.
The fastener kit 94621F (included) contains: 8 hex bolts (Grade 8, 5/8"-11 x 2.00"), 8 conical washers (5/8"), 8 flat washers (5/8"), and 8 hex nuts (Grade 8, 5/8"-11). These fasteners are used to bolt the Goosebox to the trailer wing set.
Required tools include: 15/16" socket, 15/16" wrench, a torque wrench capable of reaching 250 ft-lbs, lithium grease, and equipment for lifting approximately 250 lbs. Two people are recommended for the air fill/adjustment process.
Yes, the fastener kit 94621F is included with both the 94920 and 94980 Goosebox models. It contains all bolts, washers, and nuts needed for installation.
Two people are recommended for the air fill and adjustment process. The manual states that filling the Goosebox air system may require 2 people: one to fill the air valve and one to watch the air inflation visual indicator. For the physical bolting installation, the manual does not explicitly require two people, though lifting equipment for approximately 250 lbs is needed.
Before installation, ensure the truck is level and the trailer is on level ground. The truck should be in park with the parking brake applied. Place wheel chocks firmly against the front and rear of each trailer tire to prevent any forward or rearward motion. Lower the truck tailgate if necessary and monitor clearance between the lowered tailgate and the trailer, as some truck and trailer combinations have little or no clearance. Do not remove the wheel chocks until all installation steps are completed.
1. Place wheel chocks firmly against front and rear of each trailer tire. 2. Lower the tailgate if necessary. 3. Ensure the gooseneck ball is locked within the truck bed housing and is a 2 5/16" diameter ball. 4. Ensure the Goosebox coupler handle is in the locked position and not limited by the pull cable or debris. 5. Back the truck slowly into the trailer until the Goosebox coupler is above the gooseneck ball. 6. Lower the coupler onto the gooseneck ball; the handle will open then snap shut. 7. Ensure the handle has returned forward to the locked position before towing. Visually inspect from the side to confirm the gooseneck ball is completely recessed inside the Goosebox coupler. After the handle is locked, raise the trailer jacks to ensure the Goosebox is locked onto the ball.
1. Ensure the truck is in park with the emergency brake on. 2. Place wheel chocks firmly against front and rear of each trailer tire. 3. Lower the trailer landing gear until its feet rest on firm ground. 4. Lower the truck tailgate. 5. Disconnect the power cable and breakaway switch cable. 6. Using the pull cable, pull the handle back and hook the cable stop onto the bracket to move the handle to the unlocked position. If necessary, adjust the cable stop by loosening the small set screw (Allen wrench size 0.050"), moving the cable stop, and retightening. 7. Raise the trailer until the bottom of the coupler is approximately one inch above the top of the gooseneck ball, then release the cable. 8. Ensure the coupler latch returns to the locked position.
The 5/8"-11 x 2.00" Grade 8 bolts and flat washers are installed from the outside of the trailer wing. The 5/8" conical lock washers (with the crowned shape and teeth) and 5/8"-11 Grade 8 nuts are installed on the inside of the Goosebox, with the teeth of the conical washer against the inside of the Goosebox. All 8 bolts are then torqued to 210 ft-lbs. During installation, be mindful of clearances, wiring, and other obstructions, and use caution to avoid distorting the vehicle structure.
All 8 bolts (5/8"-11 x 2.00" Grade 8) must be torqued to 210 ft-lbs. A torque wrench capable of reaching 250 ft-lbs is required.
The bolts and nuts are Grade 8. The fastener kit includes 8 Grade 8 hex bolts (5/8"-11 x 2.00") and 8 Grade 8 hex nuts (5/8"-11).
The manual requires that trailer lights, turn signals, electric brake connections, and breakaway switch connections be made every time you tow, no matter how short the trip. These are safety-critical connections. Check the operation of all connections, including the electric brake manual control, before getting on the road. The breakaway switch cable should be long enough to allow for the full turning radius of the truck and trailer.
Never exceed the manufacturer's recommended towing capacity of the truck. The combined weight of the trailer and its contents must not exceed the lowest rating of the truck, hitch, and trailer. For the 94920 Goosebox, the maximum gross trailer weight is 20,000 lbs. For the 94980, it is 22,500 lbs. Both models have a maximum pin weight of 4,000 lbs. Exceeding these ratings can result in trailer separation, serious injury, or death.
Before towing, ensure: the truck manufacturer's tow ratings are understood and not exceeded; rearview mirrors are properly adjusted; the brake controller is properly adjusted and operating correctly; the breakaway switch is securely mounted and free from obstructions; safety chains (if equipped) are securely mounted and free from obstructions; all coupling surfaces are clean of dirt and debris and lightly greased; E-rated tires are used and properly inflated; airbags (if equipped) are inflated to proper pressure; the truck is level when the trailer is attached and loaded; clearance between the truck bed top and trailer underside is approximately 7 inches; the truck and trailer are loaded evenly and do not exceed manufacturer's ratings; and the trailer is not loaded heavier behind the axle(s).
Yes. The Goosebox has multiple pinch points that can cause serious injury. Keep fingers and all other body parts away from the pinch points. The coupler may have sharp edges. The only safe place to touch is the air inflation valve. Placing a body part or object anywhere else could cause damage or serious injury.
No. Never allow people in the trailer while towing, under any circumstances.
No. Do not tow one trailer behind another (tandem towing), as this may cause loss of control.
Stop immediately and make a thorough inspection of the entire towing system. Correct any problems before resuming travel. Severe bumps can damage the towing vehicle, hitch, and trailer, so drive slowly on rough roads.
Before each trip: 1. Check the condition of all towing equipment and keep it in proper working condition. 2. Check that all bolts and nuts are properly tightened. 3. Check that the airbag pressure is set for your vehicle and loaded trailer (note that airbag pressure can change with temperature when not in use). 4. Check the functionality of the coupler pull handle to ensure it moves in both the locked and unlocked positions. 5. Check the gooseneck ball, coupler, chains, and all other connections. Re-check at fuel and rest stops.
Regular maintenance includes: 1. Before each use, grease the coupler shaft from the fitting on the backside of the coupler. 2. Clean and grease the gooseneck ball. 3. Before each use, grease the main pivot shaft from the fitting on the inner bushing (deflating the airbag may make this easier). 4. Inspect the Goosebox for any damage or excessive wear. 5. Once per season, fully deflate the airbag and then refill it. 6. Perform normal maintenance when taking the unit out of storage. 7. Before each trip, check that all bolts and nuts are properly tightened and that the airbag pressure is set correctly.
Lithium grease should be applied before each use at three locations: 1. The coupler shaft from the fitting on the backside of the coupler. 2. The gooseneck ball (clean it first). 3. The main pivot shaft from the fitting on the inner bushing. Deflating the airbag may make accessing the main pivot shaft fitting easier.
Once per season, fully deflate the airbag and then refill it. The airbag is equipped with an automatic air relief valve that will activate and release air to a safe level if the airbag is over-inflated. The airbag can lose pressure with temperature changes when not in use, so check the pressure before each trip and adjust as needed for your vehicle and loaded trailer.

The warranty is valid only if the product is returned for inspection and testing, the inspection discloses material nonconformance not caused by misuse, neglect, wear and tear, improper installation, unsuitable storage, improper repair, alteration, or accident, and the product was installed, maintained, and used in accordance with the instructions. Product replacement is the sole remedy. To make a warranty claim, contact Horizon Global Corporation at 127 Public Square Suite 5300, Cleveland, OH 44114, or call 1-800-632-3290. Retain your purchase receipt to verify the date of purchase.
The Goosebox works with any pickup truck that has a 2 5/16" diameter gooseneck ball locked within the truck bed housing. Confirm your truck has this ball and that the Goosebox can be bolted to your trailer's wing set (Lippert 1621, 1716, Rhino, or others—contact Technical Service at 1-800-632-3290 for compatibility with other wing sets).
You need a 15/16" socket, 15/16" wrench, a torque wrench capable of 250 ft-lbs, lithium grease, and equipment to lift approximately 250 lbs. The fastener kit is included.
The manual does not mention drilling. Installation uses the included fastener kit (8 bolts, washers, and nuts) bolted to the trailer wing set. However, consult the manual for your specific trailer wing set or contact Technical Service at 1-800-632-3290 if you have questions about your installation.
All 8 bolts must be torqued to 210 ft-lbs using a torque wrench capable of reaching 250 ft-lbs.
The 94920 is rated for 20,000 lbs gross trailer weight; the 94980 for 22,500 lbs. Both have a 4,000 lbs maximum pin weight. Never exceed your truck manufacturer's towing capacity or the lowest rating of any part of the towing system.
Before each use, grease the coupler shaft, gooseneck ball, and main pivot shaft. Check all bolts and nuts are tight and airbag pressure is correct before each trip. Once per season, fully deflate and refill the airbag. Inspect for damage or wear regularly.
Maintain approximately 7 inches between the top of the truck bed and the trailer underside, and a minimum of 2 feet between the truck bumper and trailer. For off-road use, allow more clearance.
If the coupler handle is limited by the pull cable or debris, adjust the cable stop. Loosen the small set screw (Allen wrench size 0.050"), move the cable stop to the correct position, and retighten the set screw. Ensure the handle can move freely in both locked and unlocked positions.
The Goosebox airbag is equipped with an automatic air relief valve. If the airbag is over-inflated, the relief valve will automatically activate and release air to a safe level. No manual intervention is required.
The airbag can lose pressure with temperature changes when the Goosebox is not in use. Check and adjust the airbag pressure before each trip to ensure it is set correctly for your vehicle and loaded trailer.
Ensure the gooseneck ball is completely recessed inside the Goosebox coupler by visually inspecting from the side of your vehicle. After the handle is in the locked position, raise the trailer jacks to ensure the Goosebox is locked onto the gooseneck ball. If the handle still does not lock, check for debris or obstructions and ensure the coupler is properly seated on the ball.
