water leaks

We've had serious leakage issues with our TT within the first four months of owning it (we purchased it brand new). It leaked at the slide and there was a crack in the hull under the slide. This led to the floor buckling. We had it serviced under the warranty and it took three months. Honestly, I don't think they completely fixed that problem the first time because I discovered a leak at the slide again. We take great care of our TT and my husband is very proactive at looking for problems before they become worse. We also have it covered while it is in storage. Our TT is now three years old and was just used for the eighth time. While camping a week ago my husband discovered the pipe that connects to city water is leaking. The floor is buckled in three places as a result of the leaking. It also leaks at the window above our bed. This window has a cover and has never been opened because my husband wanted to prevent leaks. So, yes, leaks do happen, and they can happen early on. I would research the brand , reviews on that brand, consistent problems with that brand, and generally if people are happy with that brand.
Do problems happen with TTs? Yes, the quality just isn't there and it seems most manufacturers will not stand by the integrity of their product which is unfortunate for the consumers. So be as educated as you can.
