Because of space limits, I won't go into all the problems that I have experienced with my Axis 25.2 but presently while camping there was a water leak outside the bathroom. It wasn't there when we woke up. When I removed the access cover under the Shower I could see water dripping from the 90 on the shower cold water line. I could not reach the crimp-on band from this location so I cut a hole in the wall to expose the fittings. Crimping did not solve the problem. We went home earlier from our camping trip and took the motorhome to a local repair facility. They took the paneling off to find that two of the paneling staples punctured the hot water line in two places but did not start leaking until the staple rusted. Why would one place a staple in a wall where there is water lines running? I could see placing them where the wall support studs were but. Thor Customer Service rep could not answer that question. Nor would he even discuss some level of responsibility for the problem. "We don't know who could have put those staples there." I told him I had pictures and could send him the hot water PEX for his review. NOPE! You are SOL! Another example of Thor's quality.
We had a neighbor that had their dinning room ceiling fall onto the table. The sheet rock guy put a couple screws through the pipe going up to the shower head. Same thing. Took a few years for a screw to rust.
