Been driving my Ram 2500 around a lot lately, and it has reminded me of a couple of long term questions I had from the last time I ran a 3/4t with the NV4500. 1. Do you use the creeper gear w(1st gear)d around without a load, I have been told not using the creeper is a sure fire way to premature clutch failure. 2. Do you air up and down your E-rated tires based off of the load you are towing/carrying? When I brought the truck home, the PO had the tires aired up to 70psi, unloaded the ride and handling was awful, I pulled them all down to 40psi for the ride home and everything was significantly better.
