Will our Tundra tow this?

You would kill your truck with that load. We have a 2013 Tundra 5.7 and would stay around 6000 lbs max.

Too heavy, IMO. The length is a bit of a concern; we had a TT that was 34' from hitch to spare tire, but it weighed only about 7500 lbs when fully loaded. (We probably overloaded it a bit.) The truck handled it fine, but now that we have downsized to a TT that is 8' shorter and 1000 lbs lighter, we can really tell the difference. We now have a good match - the former one was a bit too much. I'm afraid the TT you're considering is just enough more that it would be too much. The truck will pull it, but it will be a strain with that weight.

Tongue weight alone is over your capacity. You would have a tongue weight of 1200# loaded.

For exactly what Ron listed, I recommend near 6k dry for the most capable half tons.

Towing 2011 Starcraft 28' with 2005 Ford Expedition into Tenessee and over the Jellico Pass. Trailer loaded is about 6200# and Expedition is about 6200# as well. According to Ford, GCWR for both is 14,500#. Tongue weight is 820#. Expedition has tow package with tow capabiltiy of 8,600#. Not sure on torque but think it is 3:55 something. Am I going to have a good/safe trip or will I be setting along the side of the road having a really bad day?

I tow a 33 foot Rockwood with my 2010 Tundra I have no problem with
tail wagging the dog, tows great but only weighs 7500 loaded
he tounge weight is what you have to watch.

I tow a Jayco 2013 27DSRL White Hawk with my 2012 Tundra 5.7 with tow package.
I am right at my payload capacity with 6700 lb fully loaded trailer. It tows just fine. I would not want to tow much more than this with my Tundra
