Great timing. We just ordered a new Northern Lite 10-2 LEDB and are about to order a RAM 5500 and a body, possibly from Douglass Truck Bodies. We went with the 5500 as the payload of a 4500 is not much more than a 3500, but it does hve a huge towing capcity over the 3500. I needed carrying capacity so I went with the 5500. It looks like I will need a Kelderman air suspension after reading these comments.
4500 vs 5500 is the same typical dilemma as 2500 vs 3500.
As far as I know, same frame, axles, wheels and brakes, different springs and different gvw/payload rating.
None of which matters if you’re ripping out the suspension and replacing it with aftermarket. Even the gvw ratings don’t matter once you modify the most important part of the gvw equation.
