Since you already own it, it's kind of late now to ask. I'll copy and paste what I wrote to another member about my fathers experience because it's too long to re type. Not to scare you, more of what to watch for.
My father bought a 2012 8289ws on my recommendation. I owned a Rockwood TT without any problems and never heard many complaints from others. I'm embarrassed now. Luckily he forked out for the extended warranty. It's been nothing but a nightmare since day one. The roof leaked around the shower skylight, now a recall item, then it leaked around the A/C and one of the slides. One slide was misaligned and rubbed through the vinyl flooring. Caulking was missing in several areas. The tires dry rotted within the first year. The stereo stopped working and the TV antenna never did. The dual mode water heater didn't work on electric and the list goes on. It has been back to the dealer countless times and has spent more than 6 months on the lot for repairs. It's going back to the manufacturer next month to have the entire roof replaced due to the leak damage.
We have met several others on the road with the same Rockwood and its twin Flagstaff model and many have had the same problems.
It is now back from having the entire roof replaced and all the other issues hopefully fixed. It's the dead of winter here so won't know for sure until the spring. It's not coming off the dealers lot until we can inspect it fully.
