My 2004 36 ft Mobile Suites was 1,100 lbs heavier on the kitchen side than the door side when weighed by wheel position, but only a 200 lb difference in each axle weights. It is entirely possible to have a heavy side, only way to tell is weighing by wheel position. Drive on Cat scales at the truck stops are not designed to straddle the scale to get side weights. They install poles or curbs to keep you as centered in the lane as possible. Even with the big side to side difference in my unit, it sat level and didn't lean to the heavy side. I would say Something isn't right if your off by almost 2 inches.
