We have similar boats, what kind of mileage when pulling the boat?



Taking it easy, keep it at 70, mixed with time at 55 to 60 mph, you can expect around 14 to 15.

My brother has a 2020 4wd GMC with the 5.3 gas, pulling a similar weight camper he is getting 7 to 8 under similar conditions. There is more wind resistance on the camper. We plan to pull his camper with my truck to compare mileage.
