Use your half-ton pickup for towing AND have a clean bed when youre not!
With the REESE Max Duty Underbed Mounting System you can have both. This first-of-its-kind towing solution features REESEs power puck under-bed mounting system which gives you a clean truck bed once your fifth wheel or gooseneck hitch is removed. No bulky, permanent rails above the bed to work around and take up space in the bed of your truck. With the Max Duty system, your bed stays clean and available for anything you want to load in it.
For the first time ever, you have the option of a towing solution for your Chevrolet Silverado 1500 & GMC Sierra 1500 pickup that installs under the bed of your truck, with a weight rating of 14,000 pounds. The Max Duty towing system is designed to give you the maximum amount of towing capacity out of your half-ton pickup. This advanced under-bed mounting kit gives you the versatility to mount and tow with either the REESE 14K M5 5th wheel hitch (Part# 30947) OR the REESE 14K gooseneck hitch (part#30946), both of which fit into the same, unique Max Duty puck pattern. This unique four-puck pattern makes installation quick and simple, with a wider mounting footprint for increased stability and it also makes it easy to connect or switch between the two options. Like all REESE products, this one-of-a-kind rail kit is tested to exceed SAE J2638 standards and is backed by a limited lifetime warranty. So make it easy. Make it fun. Make it the REESE Max Duty Underbed Mounting System, so you can make the journey as enjoyable as the destination.

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.

Plastic bed liner inserts cannot be reinstalled after the MAX DUTY Mounting Kit is installed. If you have a plastic bed liner, you will need to remove it permanently. Spray-on bed liners are acceptable and can remain.
No. The manual requires you to lower and remove the spare tire before installation. Consult your vehicle's owner's manual for the detailed procedure.
Four people are recommended for removing and reinstalling the pickup bed. The manual also mentions "helping hands of an assistant" for detaching tailgate tether cables and removing the tailgate. Additional people may be helpful for other steps, but four is the specific recommendation for bed handling.
Use 4x4 blocks or stands similar to how the bed is supported while installed on the truck. Do not set the pickup bed directly on the ground. The manual notes that 4x4 blocks can be used to provide clearance for installing center rails.
You must disconnect the LH (left-hand) and RH (right-hand) wire harnesses located on the hitch behind the bumper. The manual notes that due to model and option variations, your vehicle may have additional wiring and grounding attachments, so check carefully before proceeding to avoid damage.
The brake junction bracket is located along the inside of the driver's side frame rail. You must remove it using a 13mm socket to free the bracket from the frame rail before installing the frame brackets. The retaining bolt will not be reused. After frame bracket installation, you will reattach the brake junction bracket using a new M8x40mm bolt.

1. Remove tailgate, bed liner, fuel filler, and disconnect wire harnesses. 2. Remove six pickup bed mounting bolts. 3. Remove pickup bed (optional). 4. Lower and remove spare tire. 5. Remove brake junction bracket and electrical cable supports. 6. Install frame brackets with cross rails and outer brackets (hand-tight, no torque yet). 7. Install mounting rails with inner brackets. 8. Check puck mounting locations for squareness. 9. Drill pilot holes in pickup bed and verify alignment. 10. Drill 3-inch holes in bed. 11. Reinstall bed and torque all fasteners in the specified sequence. 12. Reinstall fuel filler, urea filler (if equipped), wire harnesses, and tailgate. 13. Verify puck clearance and check exterior lighting.
Frame bracket installation includes: (1) Cross rails (item 1) positioned on top of frame rails; (2) Four ½"-13 x 1-1/4" carriage bolts (item 11) inserted into square holes on cross rails; (3) A bolt leader (item 17) used to thread a ½"-13 x 1-3/4" carriage bolt and 1/4" x 1" x 3" block (items 15-16) through the frame locator hole and bracket locator; (4) Outer brackets (items 2 and 3) secured with conical washers and nuts (items 10 and 13), hand-tight only; (5) Cross rails secured to outer brackets with four ½" flange nuts (item 12), hand-tight only. Do not tighten fasteners at this stage—they should allow movement in the brackets and cross bars.
Mounting rail installation includes: (1) Inner brackets (items 4-7) positioned along frame rails, aligned with outboard frame brackets (items 2 and 3); (2) Eight ½" x 4-1/2" carriage bolts with spacers, conical washers, and nuts (items 8, 9, 10, 13) installed as shown in Figure 7; (3) Eight ½" x 1-1/4" carriage bolts and flange nuts (items 11 and 12) installed using the included bolt leader (item 14). Do not torque fasteners until the bed holes are drilled and aligned with puck centers.
Check puck mounting locations for squareness as shown in Figure 8 or by using the REESE MAX DUTY 5th Wheel Hitch 30947 or MAX DUTY Goose Hitch 30942. The center-to-center dimensions should be equal at approximately 33-3/16" (843.4mm). Do not torque fasteners until the bed holes are drilled and aligned with puck centers.
You must drill four holes in the pickup bed: first, four 1/8-inch pilot holes to verify alignment with puck centers, then four 3-inch holes using a hole saw. The pilot hole locations are specified in Figure 9 with reference dimensions: 30-13/16" (782.3mm), 46-15/16" (1192.2mm), 29" (737mm), 14.5" (368.5mm), 16-3/16" (410mm), and 10-3/4" (273mm) from the rear edge of the pickup bed and inside surface of the wheel well.
Use caution when drilling to prevent bed damage. Drill 1/8-inch pilot holes first and verify alignment with puck centers before drilling the final 3-inch holes. You may need to adjust pilot hole positions for proper alignment. It may be necessary to modify the exhaust heat shield for proper fit. After drilling, deburr the rough edges and apply corrosion preventative to the raw edges of the drilled holes.
The manual states that it may be necessary to modify the exhaust heat shield for proper fit, but this is not always required. After drilling pilot holes and checking alignment with puck centers, you can determine if modification is needed.
Yes. The installation requires drilling four 3-inch holes in the pickup bed, which is a permanent modification. Plastic bed liner inserts cannot be reinstalled after installation. The mounting system is designed to remain on the vehicle.
The vertical cross bar ½"-13 carriage bolts (item 11) should be tightened to 93 ft-lb (126 Nm). Hardware near the fuel tank may require the use of a crowfoot wrench.
The frame brackets ½"-13 x 1-3/4" and 4-1/2" carriage bolts (items 15 and 9) should be tightened to 85 ft-lb (115 Nm).
The brake junction bracket M8x40mm bolt (item 14) should be tightened to 18 ft-lb (25 Nm).
The pickup bed bolts should be tightened to 50 ft-lbs (68 Nm).
The fuel filler pipe screws should be tightened to 44 in-lb (5 Nm).
The urea filler pipe (if equipped) should be tightened to 22 in-lb (2.5 Nm).
Do not torque fasteners until the pickup bed holes are drilled and aligned with puck centers. After alignment is confirmed, tighten all hardware in the following order: (1) Vertical cross bar ½"-13 carriage bolts to 93 ft-lb (126 Nm); (2) Frame brackets ½"-13 x 1-3/4" and 4-1/2" carriage bolts to 85 ft-lb (115 Nm). Then install the bed and torque the bed bolts to 50 ft-lbs (68 Nm).
After the pickup bed is reinstalled and aligned, reconnect the LH and RH wire harnesses that were disconnected during the initial steps. The manual notes that due to model and option variations, your vehicle may have additional wiring and grounding attachments, so ensure all connections are properly restored.
Check for adequate clearance between the trailer and the rear of the cab and the rear of the truck box before installing the hitch. The manual does not specify exact clearance measurements beyond this general requirement.
All trucks have fuel lines, brake lines, and electrical wiring located along the vehicle frame where the rail kit installs. Carefully examine the location of these systems before installation and ensure you do not damage them when positioning hitch components. Be careful when drilling holes, cutting sheet metal, and tightening fasteners to avoid limiting the integrity of these systems.
After installation, inspect the pucks for proper placement: puck grooves should sit above the drilled pickup bed holes, and there should be a minimum 0.039" (1mm) clearance between the pucks and holes in the pickup bed. Clean any debris from the pickup bed and check the vehicle exterior lighting for proper operation.
There should be a minimum 0.039" (1mm) clearance between the pucks and holes in the pickup bed. Puck grooves should sit above the drilled pickup bed holes.
Check the vehicle exterior lighting for proper operation after installation is complete. This ensures that the wire harness reconnection and any electrical work did not damage the lighting system.
Periodically check and re-torque all hitch fasteners. The manual does not specify an exact interval, so consult the manufacturer or your vehicle's owner's manual for recommended maintenance schedules.
The primary maintenance requirement is to periodically check and re-torque all hitch fasteners to ensure they remain tight and secure. This helps maintain the integrity of the installation and safe operation of the hitch system.
Adjust the pilot hole positions as needed for proper alignment. It may be necessary to modify the exhaust heat shield for proper fit. Do not proceed with drilling the 3-inch holes until alignment is confirmed. Check that the mounting rails are properly positioned and that the puck mounting locations are square (center-to-center dimensions should be equal at approximately 33-3/16").
Insufficient clearance between the pucks and pickup bed holes indicates a misalignment issue. The puck grooves should sit above the drilled pickup bed holes with a minimum 0.039" (1mm) clearance. If clearance is inadequate, the mounting system may not function properly. Verify that the bed is properly aligned and that the pilot holes were correctly positioned before drilling the final 3-inch holes.
Check that the LH and RH wire harnesses were properly reconnected after bed reinstallation. Verify that all electrical connections are secure and that no wires were damaged during the installation process. If lighting still does not work, consult your vehicle's owner's manual or contact a qualified technician to diagnose the electrical issue.
