2025 Limit Towing Over Mountains

Hi All, I just got a 2025 Limited and am loving it!!!
We are looking at getting a camper when full weighs 6200lbs. Has any one towed the same weight over a significant mtn range like the Sierras or Rockies? It said it’s good up to 11,400lbs but Im curios how your transmission handled it if it was a struggle at all?
Any help would be truly grateful!
Thank you
Scott

I was thinking of the exact same example.

 

I tow that weight (and more) somewhat regularly at elevations between 5000 and 8000 feet, climbing several 10% grades, with my 2nd gen truck. No issues.

The 3rd gen has some refinements over the 2nd gen but two of the biggest advantages in that situation are forced induction and the 10 speed transmission. The turbos help mitigate power loss due to decreased air density, and the transmission gives a broader range of gears to help both climbing and descending (via engine braking). From what I've seen of the 3rd gens, you shouldn't have any issues.

The coil sprung rear end - assuming you don't have the factory air ride - is a little soft for tongue-heavy trailers such as travel trailers, so you might want to look in to suspension enhancements. But a WDH is a very good starting point.

Edit: I'm trying to find the comment, but I believe Mike Sweers answered a question a while back about de-rating tow limits with altitude as Ford does with the F150. His comment was basically: we don't need to de-rate the tundra's towing capacity for altitude.

 

Yeah....not something we have to worry about in South Texas.
The biggest hills we have to contend with are over passes.
