That's what i'm going to do, I heard these rancho shocks are pretty much junk. I did put the air lift on today and it looks good. I'm pulling a 37ft bumper pull camper that weighs 8500# dry, which I failed to mention. I bounced to kingdom come on those Alabama interstate 10 bridges and was concerned. I still think the springs look bent upward in the center which is not normal in my book. I will schedule to have a tech look at it and let you guys know what the diagnosis is.
Oh and the tires it came with are the Firestone Transforce AT with the 17 inch wheel. I got nice aftermarket wheels and toyo tires of the same size.
