Welcome to the forum.

All equipment is different, every setup varies somewhat, based on only your truck?
Usually a truck running 35"s has been leveled too? Getting a 5r's axles loaded properly and maintaining proper bed / front cap clearance can indeed be a real challenge if even possible. How much towing are you planning?
The process of physically adjusting a hitch an / or pin box is not that demanding with the correct tools. You'll possibly want to replace the deformed lock washers and re- torque appropriately. Best of luck.
