Drive em up or winch em up?

I bought the trailer with the interior finish pkg. Afriend of mine used a rubber floor he purchased from Griot's Garage. The first year we towed with a 5.7 liter in a Z71 1/2 ton, the next year we went to a 6 liter 3/4 ton. This year we bought a HD2500 with the Duramax diesel and Allison trans. To go anywhere from here we have to cross the mountains and the new truck has really been fun to tow with. We would get about 9 mpg with the 6 liter and are getting 12-13 mpg with the new truck at 65mph. Jim
