My 213 has 11,500 miles on it of which I have put half on it mostly towing my 05 GMC Sierra full size pick-up (4,400 Lbs) or my wife's Honda Accord (3,000 lbs?) plus a tow dolly, gets about the same mileage. It does seem to be getting better though. Our first trip to Mobile, Al was bobtail and we averaged about 11.5 over all with a lot of city driving (no toad) driving about 800 miles round trip. On subsequent trips to Mobile we towed the pick-up (4 wheels down) and got 10.5 to ll.5 depending on speed and wind.
Last month we journeyed to Kansas City, Mo for a 1500 mile trip over 8 days towing the Honda. Towing the Honda was easier than using a tow-bar on the pick-up. Plus it made the RV ride much better. Almost every fill-up averaged 11.5 mostly @ 55 60 mph range through Alabama, Mississippi, Tennessee, and Arkansas. Then we ran interstates to Kansas City and back home through Illinois, Kentucky, and Tennessee averaging 11.8 mpg every tank-full running 65 mph.
I think with it getting more broke in it is getting better MPG, plus I think it is geared for the 60 - 65 mph with the 4.11 gears.
We love the size and drive-ability of the R-Vision Trail-lite, but like every-one else, we are working on the rattles.
