Those smart alek responses are why fewer and fewer PUP owners frequenting this site. I would always welcome helpful suggestions from any person on this site but it seems like owners of other styles of RVs are always looking down on PUP owners and providing answers that are unhelpful at best and often just condescending. I'm not sure why someone like that would take the time to even respond like that.
PartyMarty, here are a few sources to look at regarding some of the leaks encountered with Chalets. Most leaks are with older models but something to be cognizant of regardless of manufacturer, model or year.
Three different areas of leaks:

The long and the short of it is that every camper can leak. I would not have a problem looking at a recent model Chalet at all as they corrected much of the causes. However, I don't care who makes a camper - if the owner(s) has not kept up with maintenance, inspected and corrected any caulk or seam failures, then that camper is going to have a problem.
It comes down to you doing a great visual inspection and interview of the seller if you are buying used. If you are buying new, then try to do research on the specific, recent years' models.
You could help us out by letting us know if you are looking at new or used and possibly if you have some specific models in mind.
It would appear that by your location in your profile that you are right to be concerned about leaks. Most leaks can be avoided or greatly reduced by proper storage when the camper is not in use - breathable covers or completely covered by a garage of some sort. If your camper's only exposure to the elements and UV is when you are actually camping, you will keep a "mint" looking camper for quite a long time. That's one of the benefits of having a collapsible format.
Good luck and let us know what else you think about.
