We Tow a 28' TT with a Tahoe and I'll tell you right now at that weight you'll be better off with the capacity and the longer wheelbase of a truck. We have a family of 5 and a SUV is preferred but a truck will be next. Soft coil springs, passenger tires along with a short wheelbase are just a few of the things we've had to work around. But if you insist on sticking with a SUV the 2016 Tahoe has an eight speed tranny vs the 6 speed of the Toyota as well as a few other nice features (btw I am biased as a Chevy guy).
