Montana Sky, alot depends on driving speeds, terrain and headwind. On average I would say I get about 11 mpg pulling my 3670 running 65 mph. I just returned home from a 1000 mile round trip and averaged 11.5 mpg. I have however averaged far less on a trip to texas in Jan with a 15 to 20 mph headwind. When I figure feul expense before a trip I figure 10 mpg just to be on the safe side.
Rick.
