Do the math on your truck and call trailer owner and have him do his math and you will know what you are dealing with except how much rear of truck will drop with the pin weight. When we bought our 2014 Keystone Alpine 3500 RE the dealer was 200 mi from home. I told dealer I needed 50" pin height at level. When we got there I hooked up and put 60 psi in the airbags on my 2010 Ram 3500 4x4 megacab and have had no problems for over 10 k mi towing. Take time now or suffer later. JMHO.
