I've struggled with the same issue. Been thinking of a GMC Sierra or Chevy Silverado. I currently have a GMC Yukon Demali 6.2 L 3.42 gear, AWD, air ride and HD tow pkg rated at 7900lbs tow capacity. I now pull a 28ft (+ 3 ft tongue) at 5400lbs dry, est 6400lbs loaded. Was thinking the longer wheelbase on a pick up and a 3.73 gear would be beneficial. After towing this new TT in the NC mountains, I'm really wondering if I need to make the move. The 6.2l Is a beast and handled 6% grades with no problem...used tow mode and most often on cruise...55-60 mph? Love the benefits of the SUV, but a pick up has certain appeal, such as utility. Just me and my wife and 3 small dogs. I leave the third row seats out, and limit my loads in the Yukon. So the longer wheelbase Nav with 4.10 gear is probably a good fit. Suburban or Yukon XL configured corrected would work as well.
Still not sure if I will make a move to a pick up.
