Sorry to hear about your difficulties. We bought a 2008 197 in 2011. It was a nifty little trailer. I discovered that the bolts to hold the rooftop unit were not tightened. No harm came of it, as I noticed a little dribble of water on the floor, after a rain. Luckily it was at home at the time, and I fixed it myself. Afterward, I noticed on this site that lots of people were finding the same thing.
We traded the 2008 last year for a 2012 197. It had many improvements, mainly a pull-out, a bigger bathroom, and electric awning, and a much better layout in general.
Too bad the dealer didn't point out that a larger a/c was available on the later serial numbers.
No doubt they knew this.
Don't be discouraged. Hang in there. I have never camped with a trailer, neither has my wife. We have only used it once, so far. We plan on going to the Yukon this summer, so I have been trying to find all the bugs while still around home. Here's my latest performance: http://www.jaycoowners.com/showthrea...overnight-camp
