I thought you had 3.42s ?? Then I would def call bullshit
I have towed anything and everything with one of every GM V8 model made in the last 30 years
Seriously though, my 07 with 5.3/3.73 got 8 towing a 6000 pound TT. Worse in the mountains and horrible over 62 MPH






@ Darky.Because y'all are hatin'
If weight was really that big of a factor, I'd lose/gain more than 1 MPG pulling Super B... A difference of 96,000lbs between empty and loaded. The fuel bulkers get a consistant 3 - 5 MPG better than the hopper bottoms I pulled, with the same weight.
