I am planning on purchasing a tt with a dry weight of 5500 lbs. I am also looking for a used half ton truck between years 2004 and 2008. I am considering a 2006 dodge ram 1500 Laramie with a 5.7litre ...
That sticker in the door jam will help a lot. Back in '06 I think the Ram 1500s had gone to the 5 speed transmission, which was stout enough, but had a wide spread between 1st and 2nd, or 2nd and 3rd. Don't remember which. Hopefully it has at least 3.55 gears and preferably 3.92. That's the stuff I'd be looking at first.
