I guess a SAS and 35x12.50s with a lift and roof rack sucked it down.
I get 17mpg if I keep a light foot these days. Sans roof rack.
Regards protecting the pictographs, I agree to a point - though in the NP, we had a ranger drive up to us Baja style and jump out of the truck to make sure we had not approached an overhang that had pictographs. We had, and we did not tell her we had, and there was no signage saying you shouldn't, and we did not touch anything, just look - but her solution to protecting it was to make sure no one ever saw it.
