Met a guy at an RV show last weekend who pulls a 28' TT with a Nissan Armada, he said he absolutely loves it and was shocked at the amount of power he had the first time he hauled his camper.
There are about 10,000 threads here on towing capacity / GVWR / etc. but when I saw 7,000 ship weight and 7,200 tow rating (Jeep) alarm bells went off. My moto now is that my vehicle should be rated for 125% (towing and payload) of the yellow sticker weight + weight of all my gear and people. I sold myself short in the TV choice once and I'll never do it again. Looks like Armadas are rated up to 9,000 lbs, that would be a better fit for the 7,000 TT. Just my opinion and you know what they say about those :B
Good Luck!
