There are two soft spots in the floor of my Cyclone 3210 from moisture damage. The first is located at the corner of the entrance door, right under the refrigerator. There are also water stains at the bottom of the entire refrigerator cabinet. Almost directly across, on the other side of the unit, another soft spot has appeared at the front of the opening for the slideout. There has never been standing water in either location, the damage is limited to the subfloor only, and there is no other water damage anywhere that I can find. The best explanation that I can come up with is that water is coming in a tiny breach in the vapor barrier on each side. Both leaks are located directly in front of the wheels, and both locations have an opening through which water coming off the front tire at high pressure could penetrate. Has anybody had a similar problem? Can anybody offer an alternative explanation? Obviously, I need to be sure that I have found the leak, and repaired it, before I fix the floor. Any input is appreciated.
