I owned a new 2013 Thor ACE 27.1 for 3 months. Took a loss and traded it in on a new 2013 Winnebago Vista 27N. Not happy about loosing the money but very glad to be rid of the ACE. The ACE had very poor handling, wandered all over the road, the fit and finish was poor, lots of rattles and bangs. Check some of the other threads about ACE handling. I had multiple water leaks, exterior and interior trim pulling off, one pocket door pulled off the rollers and jammed blocking the bedroom, and those are just the high points. When you are going through an ACE just for fun try out the throne. Unless you're over 6 feet, your toes will barely touch the floor.
The Winnebago handeled well without any add-ons or modifications right from the beginning. The fit and finish is good, cabinets are sized to be useable and are good quality. I only had two very minor warranty issues with the Vista
