I have a 2013 Ram 2500 with aftermarket wheels and tires. Currently at the tailgate, the height of my bed is 59-60". We'll be delivering our 1st FW on wednesday, and im starting to get concerned...
There's more to it then that. You need to be able to tow reasonably level or you risk s****ing the ground with the back of the fiver. Trucks have been getting taller each year. Definitely put the original tires and wheels back on. You may have to flip axles to raise the trailer as well. Good luck with the new rig.
