I'm on trailer #4 and my Forest River Flagstaff has so far been the best of them all in terms of quality and features (compared to Fleetwood and Jayco).
Now don't take that to mean they are without flaw! You can buy even better RVs if you have the money to spend. But as a mid-range rig Forest River makes a good product. Just keep in mind that RVs in this price and quality range are going to have some things that need to be fixed, even when the rig is brand new, especially if you move around a lot.
