I have a 2012 Nissan Armada (9000 lbs capacity) with the Equalizer 4Pt Dual Sway control and you can tell that your pulling something heavy, but after three trips and some hilly terrain, I have not had any white knuckle experiences.
The last trip we took was to Branson, MO and ot was hilly!!! Again, I did not have any white knuckle experiences, but I did get a whopping 7.2 mpg on that section of the trip.
We had 7 people and a lot of stuff for a 10 day trip and after weighing it on the CAT Scale, we came in at 14,300 pounds and by GCVW is 15,100. That is pushing the limit and I won't do that very often, but the Armada did surprisingly well.
I would prefer a three-quarter ton Yukon XL, but my wife does not want to drive that as a daily driver.
Net net, you're going to fell the camper behind you, but it is worth it, because this is a roomie TT and you will creat a lot of good memories!
Good luck and have fun!
