I just bought a truck to pull a fifth wheel camper with. The rails are already mounted in the bed. Will all hitches fit my rails? Thanks in advance for the help.
Welcome to 5ers. I'd test fit at the dealer before buying. If it is close but tight, sometimes you can loosen the rail bolts seat the hitch and re-torque to spec to make it fit. Post your first impression towing, and backing.
Do you know the manufacturer of the rails? For the most part, they are standardized, but not all. I would do a little checking, before buying a hitch, to be sure of fit.
