thoughts on these 3 or 4 brands??

We are going into our 5th year with our Rockwood 8281 Signature Ultralite. We have had only one problem-and--main slide motor went out this past summer. Other than that, trouble-free. We've taken several long trips with no problems; most of our trips our local weekends. We have 3 kids and a dog and our unit has held up well. Before the fiver, we had a Rockwood Roo hybrid for 4 years with no problems. So our Rockwood experience is overwhelmingly good. But you may hear contrary experiences from others---pretty much true for the mainstream brands.
