towing

I just purchased a 2020 Passport Touring AWD, and I'm searching to learn if anybody has experience towing through mountain passes with the Passport. My family has a tent trailer (GVWR @ 2,151 lbs fully loaded) we frequently take to Glacier National Park, or Yosemite National Park...basically...

So I bought the 2019 Passport Touring and added the dealer installed towing package. With this, vehicle should be able to tow up to 5,ooo lbs without difficulty. Well I'm here to say, it was an epic failure. I was towing my Aluma trailer (916 lbs) and my Indian Chieftan Limited (834 lbs)...
