I'm guessing that it is just geared to pull a big heavy stacker, not a jeep.

Pulling a stacker w/ our single axle would not be good, it would certainly put it outside of GCWR.

We recently pulled an 11k lb race trailer (i know its not a stacker) and our mpg wasn't effected....we maintained our steady 10 mpg.

that is....until i ruined it by racing a MB/Sprinter Camper Van & Trailer combo up the Oklahoma interstate hills.....that had us down to 8 mpg.

IMO the coach rode and tracked better (less wandering) w/ the 11k extra lbs.
