I also have a 288BHS. I took it back for a few things, like the thread was loose on a cushion, and the AC seemed to vibrate. They fixed every thing I ask, and did it well. They also inspected the slide seal, and replaced it unasked.
Other than that. I've been happy with it. BTW. The AZDEL walls, make the TT much cooler in the summer.
