Clearance Between Bed Rails and Fiver. Yikes!

Welcome to our world. We ordered our 2014 2 wheel drive single cab Ram 3500 Ram dually in July 2013 before anyone realized how much higher it would be when it actually showed up in October. Yikes. We had to have step installed on the truck just to climb into the darned thing and we're NOT short. Then we realized your dilemma when we turned into a fuel station and almost hit the bed rail on the truck with the 5'er. Double Yikes!! We headed to Vegas and found a shop who could lower our 5th wheel we were able to use another set of bolt holes that were in our Mor/Ryde suspenion. They also dropped the pin box so we have a very good amount of clearance now-thank goodness.

I was about to place an order for a 2014 3500HD 4x4 Ram, but went to dealer's lot first to take some measurements. If I want to tow my fifth wheel level, it looks like I'm only going to have 2 inches of clearance between the bed rails and the underside of the fifth wheel nose.
Our truck now has a slight nose up attitude but nothing offensive. We did not need air bags with the heavy duty suspension that this truck has which is a good thing because that would have made us higher yet and less clearance. Hope this helps. Hugs, Di

Currently have a 10 year old GMC Duramax 2500HD 4x4 with plenty of clearance. The height of the new Ram bed is 2.5 inches greater than the Duramax and the depth of the bed is 2 inches greater. That puts the RV 4.5 inches closer to the bed rails if I keep the RV level!

I could raise the fiver hitch height and lower the pin box, but that's going to make the RV tow with the nose up and tail down.

Am I understanding and calculating this correctly?
