On mine I get 11 empty. I pulled a gn trailer with a total trailer weight of 18,500 lbs from Houston, TX to GAllup NM and got 8.1. You are not doing to bad I don't think. Mine has 4.61 gears. I try to drive about 63-65. Sure wish I could rig mine for an aux fuel tank. having two 50's is not much fun. If it were mine I would not cut the exhaust. May could try a more open muffler or a big-rig tuner but I admit I don't now a lot about them.
