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...
Really depends how much pin weight you have. More weight means the truck will sit lower. Hook it up and see how it looks on level ground. The RAM's settle a lot. Ideally the truck will be sitting level with the RV attached and loaded for travel. Like this.
