We love ours. A couple of minor issues that were taken care of under warranty but nothing major.
Have no desire to change it for something else. A few mods like taking out the sofa and installing theater seating group from RecPro, satellite dish, washer/dryer, etc. Haven't done anything about handling, but having been a road driver for a major trucking company for 40 yrs, I don't have any issues with it in that regard.
We also have 6300 mi. on ours, it had 1200 when we bought it, so the mileage is similar. We prefer the camping side of the experience, not the traveling side.
Obviously.
