I really should try lowering the tire pressures in the Ram. They are 65psi front / 80psi rear from towing, and the ride is pretty jiggly (Bilsteins notwithstanding).

Yeah, that must be a harsh ride when not towing.

The years we spent traveling (and towing) full time in our RV's taught me so much about tire pressures. I only use the data on the door jam as reference. You really need to know the pressure/weight range info from the tire manufacture. (and have a good idea/ or weigh your axle weights)

It's really not harsh at all, but it could certainly be better.
