Our 320 hit the one year mark last September. In that time it saw the dealer 3 times under warranty. Here is a list of the problems, but first I have to say we are extremely pleased overall with the unit, not just the layout which we love, but the overall construction and choice of materials (with a few glaring exceptions.)
1- tires. They were horrible and under rated. I experienced three complete sidewall failures in 12 months, 6K miles of towing. I have replaced them with a much better and heavier tire.
2- hole in roofing material. I documented this here, but when installing a roof vent cover I noticed a nail or other object sticking up under the roofing membrane that caused a pinhole. Coachman at first refused to do anything. The dealer kept pushing and finally the agreed to patch the area. I objected and asked they cut out the area and install anew roof vent as I liked that better than a patch on a new roof. They relented and paid labor (I had the parts myself.)
3- water pump spring leak, dealer sent me a new one and I replaced it.
4 - various leaks - roof a/c, toilet, sink, slide seals. Dealer fixed several, I fixed a few. I am afraid the slide design will continue to let water in during hard rain events while towing (no problems when set-up.)
5- hot water heater exhaust in camper - dealer installed a shroud around heater to direct gas out.
6 - several cabinet hardware problems, all fixed by dealer.
7- broken plate on power center - was over torqued by manufacturer, dealer replaced.
8 - installed foam bed topper, mattress is awful hard.
I have changed or added several things to suit our taste.
