We have had ours for a year; prior to that we had another Forest River product, possibly made in the same factory. Issues with our current trailer are very minor - the TV antenna seems to have been installed a bit crooked and is difficult to use, and a hole in one of the window screens (possibly occurring during transit to the dealer). Issues with the old trailer were more major (wheel hubs especially) but that may have been due to improper service rather than the way the trailer was built. Fit & finish is pretty good - these are campers, after all, not houses, so our expectations are lower than they would be for a permanent home. We like the cabinetry, perhaps not quite as well as in our old trailer, but this is supposed to be a lower-priced and lighter model.
In all we're quite happy with it, and were reasonably happy with the old trailer, to the extent that we didn't hesitate to buy another camper made by the same company. (Rockwood & Flagstaff are twins.)
