If you are interested in an SUV with 3 rows of seats as apposed to a pickup truck, there are several available choices that should have the capabilities to handle your trailer (BWT, I agree with the 8500 LB min. It's sound advice).
Anyway, a new or used Nissan Armada w/the tow package is rated up to 9000 LB (2wd). The 07-13 Tahoe/Yukon w/ the tow package is rated up to 8500 (I think. conflicting sources say otherwise). The new Ecoboost V6 Ford Expedition/ Expedition El is rated up to 9200 w/ the tow package (9100 with 4x4), older V8 models are rated at 8700-9200 lb. The discontinued 3/4 ton suburbans had 9400 (w/ 4x4) and 9600 (2wd). I believe that's about it, excluding any luxury SUV's like the Infinti QX80 or Cadillac Escalade. Personally, I would really consider looking at either a Tahoe/ Yukon or the Ecoboost Expedition(EL). DD driving wouldn't be so bad with V6 as long as you keep your foot out of it, and the twin turbo's will definitely make towing a breeze. On the other hand, Yukon's and their Tahoe twin have great towing characteristics. Try to avoid a Denali on the 2013 and back models. I find the AWD system is ok, but a big gas sucker. the 4x4 models give you more capability and mpg. Just my 2 cents.
