Of a Truck/Camper(that with kitchen/bath) combo with high MPGs. Now, I'm assuming it's going to be diesel, but I'm also curious what one can get on the half-ton campers.
My truck is deleted/tuned, so does better than stock 6.7 of my era truck. True 35" tires, leveled, and pull a 4000 lbs of trailer. 11.5-12.5 mpg hand calculated (yes, my speedo is caliberated for the tire size) is the best I do with my setup.
