I am looking at the Durango, Tahoe and Yukon Denali.
You will limit your RV choices with those. Tow ratings are fairly meaningless for larger families and RVing. A 6k dry RV will be 7000-7500 pounds loaded for a long weekend. That means 800-1000 pounds of tongue weight. I highly recommend something with at least 1500 pounds of payload.
What years are you looking at?
I test drove a Yukon Denali including towing my TT which was about 6k at the time. The power from the 6.2L/6-spd trans was great. But even my wife agreed the ride while towing was uncomfortably bouncy.
If you are going with Ford or GM full sized SUV, I highly recommend the long wheelbase version (EL, XL, Suburban). It improves stability while towing. It offers significantly more 3rd row and cargo space. And the cost is within $1k.
