68ltd, we just got back from a trip with our Jayco HT 26.5RLS towing our 19' Crestliner behind it up to and back from Jackson Lake in Grant Teton National Park. Put about 400 miles on the truck and, according to the DIC, we got 12.8 mpg for the total trip. I know, I know, some people on here will tell you that you can't trust the DIC, but over the last three years, the DIC has been within less than .5 mpg every time I have hand-checked it so that's what I use. We have gotten as high as 13.6 and as low as 12 mpg on this trip nine times. We did take a trip of about 3,500 miles last spring and got an even 12 mpg on the DIC and 11.9 hand calculated. Sorry your mileage is so poor, but I doubt you will get any better unless you step up to a little bit bigger engine or a diesel. By the way, I have a diesel GMC and wouldn't trade for a gasser for anything.
