I tow a 2012 34' 5'er with a loaded weight around 11,000 lbs. My truck is a 1996 F250 with the 7.3L and a 4.10 rearend. Last trip out, in the foothills of appalachians, mileage was 12.3 mpg while towing at 65mph. I've made some upgrades to the truck to improve the mileage, before upgrades it averaged around 10 mpg in same towing conditions.
