The TT you're looking at weighs almost the same dry as ours. I'm also planning a 2 week trip. In planning, I try to get weights of everything I think I'll bring, plus a 20% buffer because you never know. And then on top of that you don't want to tow more than 80% of your tow vehicle's towing capacity, to leave a safety buffer. And then the aforementioned passenger weight. So our SUV, rated to pull 8900lbs, should not pull more than 6400lb, which is right at our trailer's GVWR.
Just some things to keep in mind.
