We just got back from a 4300 mile road trip, towing a 39' 5th wheel with a 3500 SRW chevy, 6.6 turbo diesel, Allison 6spd. From Salem, Or. to Phoenix, Az. I averaged 12.1 mpg. From Phoenix back, through Colorado (elevation up to about 8500') and a bit of head winds I got 11.2 mpg. Total driving speed about 60-63 mph. Non towing, highway, 20 mpg or slightly above.
