We had one some years back, a 189 iirc. Very nice layout that was great for shorter trips for the 2 of us and our dog.
As to quality, they are about like all the others. Condensation in cold weather/not a lot of insulation, a worker taking a shortcut now and then (ours was someone in a hurry to plumb the toilet leading to a leak in the fresh water feed while on the road)...etc. But again, nothing you cant say about any other TT in this category. I'd buy one again if it fit my needs.
