2012 F350 SRW. Pulls fine, about 10-12 MPG Dependent on terrain, wind, lead in foot. Used to pull with a Tundra but GVWR worried me as I usually pack the bed full of stuff too. What sucked about the tundra was the 26 gallon tank. Although the Ford has a bigger tank, you really want the biggest tank possible if you're hauling this behemoth trailer.
