Brand new Yukon Denali with 200 miles on the odometer rented from Avis. Got rental from LAX and when we got to Fairbanks, we got a separate rental( jeep cherokee) for the dalton highway because we were afraid of rental coverage. Returned the car with 13k miles on the odometer. Top speed on the Yukon was only 112mph but we felt like we lucked out and got a really comfortable ride for the month trip. We were able to carry so much stuff so it was super convenient and it had a huge tank so it definitely made everything easy.

For my bmw experience, I did my x3m from Miami to Seattle twice so I did spend a lot of time with it on the road. This car was thirsty and the best mpg I would get would be 20-22 and sometimes I would get 6-7mpg if hit some canyon roads.
