Thanks for the info. The problem is I didn't buy this truck for towing, If I had I would have got one with a 373 gear and LT D rated tires. Even with the 331 gear it don't do bad. I thank the dealer didn't dial in the WD system right Because the front of the truck dropped 1" and from research and talking to a Fastway E2 tech that's to much so I added two more washers and now the front is at stock height and the back only dropped 3/4". The front is not higher than the back. Also the dealer had all the tires inflated incorrectly. One was ten pounds over. I have already looked into some light truck tires but before I go down that road I will test the new setup.
