Here's what I'm towing, 2021 Cherokee Limited AD1. 2021 Prime Time Avenger 16BH. About 2900 pounds dry, 3500 pounds loaded up with water and supplies.
Pulls good. Even on a 93 degree day on a route with a fair amount of hills, my tranny temp never got above 190. Usually stays at around 180. I average between 12 mpg to 17 mpg depending on the route and how hilly the roads are, and whether or not the gray and black tanks are full.
Does struggle to accelerate a bit up steep inclines. Would not recommend going up and down mountains unless you are full on gas and it's a cool day.
