I think they're like many other popular brands - some lemons, some especially good ones, nothing huge to complain about as a general rule. We had ours (see sig) for 6 years and did very extensive traveling. Had some trouble with wheel hubs, and as a consequence, had to replace an axle and repair another, but that may have been as much from improper maintenance procedures as from problems with the original equipment. Other than developing some difficulty with the TV/stereo system the last couple years, no complaints; we really enjoyed this trailer and found it very comfortable.
As you can see, we had no problem with buying another Forest River product when we decided to downsize a bit.
