We have one 6.2... a 2017 4x ext cab, and although it doesn't carry a camper.... it tows a trailer, 26' box (read...wind resistance) which is approx 6000lbs. It gets about 8.1 avg in the mountains. Obviously better on the flats.
I have opposite experience. When driving big vehicle in the mountains, driving in 40-50 mph range I am getting very good mpg.
Once I hit flat freeway, the speed goes one way and fuel gauge the opposite.
When I was moving from San Francisco area to Vegas, I made 3 trips with cargo trailer. Going from SF to LV loaded I always had way better mpg, than going back empty, even I always kept my CC at 60 mph. It was all in desert winds.
