Help with tow rating for 2011 Toyota tundra and new TT

That's not a good combination, IMO. We towed a TT for 6 years that weighed approximately 7000-7500 lbs loaded, and though the truck pulled it well, I always felt the tail was just a bit bigger than the dog would like. We downsized last year to a TT with a GVWR about the same as your trailer's "dry" weight and it's going much better.

Good luck with the decision.
