Recent ACE purchaser
We purchased a 2013 ACE 29.2 in May 2014, used it mostly for tailgating at football games last fall. This year, 2015, we've made a couple of long trips each followed by dropping the coach off at the dealer for problem resolution. The Jensen stereo/camera monitor works only when it wants to which isn't often. A new head unit won't be available for two months. The Lippert stabilizers quit working requiring a new controller and wiring harness which had to be made to order because the factory has manufacturing and quality problems. The slide out quit working. Actually one side would try to move on the rear side but not the front. In essence, we could not use the slide out.
Presently, the coach is awaiting the fix on the stabilizers and the slide out. It might be, we learned and we'll have to see, that the house batteries may be the problem with the slide out.
In retrospect, I realize now that the dealer did not cover some important issues that we (I) didn't know to ask about; like battery maintenance. We were shown where the hydraulics were for the leveler so but not how to check the fluid level in the reservoir. I discovered the battery switch by accidentally turning it off and having to call Thor tech support when the 12V stuff wouldn't work.
Hopefully all these issues will be resolved before our next outing next month. Otherwise, we love the vehicle. It's just almost right for two people just need to get the wrinkles ironed out.
