Yes. The manual states to remove the spare tire for ease of installation in Step 1, and to reinstall it in Step 6 after the hitch is fully installed and torqued.
You will need: a socket wrench, a torque wrench, a 21mm socket, a socket extension, and a 3/4" socket.
No. The manual explicitly states "NO DRILLING REQUIRED."
The hitch includes: 4× 1/2-13 UNC carriage bolts, 1-3/4" grade 8 (part 10-10272); 4× 1/2-13 UNC serrated flange nuts, grade 8 (part 20-00062); 2× 0.250 × 1.25 × 2.00" square hole spacers (part CM-SP3); and 2× 0.250 × 1.25 × 3.00" square hole spacers (part CM-SP19). The existing 14mm bolts and weldnuts on your frame rails are reused.
1. Remove the spare tire. 2. Remove the existing 14mm bolts from the bumper bracket on both sides and save them. 3. Raise the hitch and align it with the weldnuts from the removed 14mm bolts. 4. Reinstall the 14mm bolts on both sides. 5. Install 1/2-13 carriage bolts with SP19 spacers in the forward-most holes and 1/2-13 carriage bolts with SP3 spacers in the middle holes; install 1/2-13 hex flange nuts onto all carriage bolts. 6.

Do not exceed your vehicle manufacturer's recommended towing capacity. The hitch itself has a gross load capacity, but your vehicle's frame, suspension, brakes, and engine have limits set by the manufacturer. Always follow the vehicle manufacturer's specifications, which are typically found in your owner's manual or on a placard inside the driver's door jamb.
Periodically check the hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify an exact interval, but regular inspection before towing trips is recommended.
