We had a problem with a wet floor in front of the toilet in our '86 345. Turned out to be a leaking vacuum breaker in the toilet. No big deal. Parts are available, and easy to replace. Rob

It Could be two things leaking water into the area in front of the shower. First in the back Curbside closet is the connection for the Shower Mixing valve. We just fixed ours 3 days ago. The pipe is CPVC- a dinosaur of a pipe and difficult to find the correct fittings for(not a Home Depot rescue). Ours was Cracked at the elbow going from the spray wand hose connection to the mixing valve. It is surprising that the mount for the hose is not bolted to the wall. if you push on it or pull it it puts pressure against the actual 1/2" CPVC elbow and Pipe. and the way A/S mounted the pipe is with a wedge of Wood between the pipe and the wall. Very Surprising but I guess it worked for the first 18 years. Luckily the connections are 1/2" FIP threads. So we used PEX pipe and an elbow, if you intend on upgrading the mount now would be the time to do it. Another possible cause for the leak that we have had is in the AC drain line. Both of ours were plugged. It is a little shocking when you hit the brakes and get a chilly river down your back. The front drain overflows directly into the center ceiling cover and is channeled right to the end, and directly above the drivers seat. We had the same probem in the back- a constant drip once it is full. The solution- we used an venturi air vacuume(the kind used to service Air conditioner lines) and a normal 1/4 male quick connect with a hose clamp which seals the drain pipes perfectly. Once you pull a good vac the lines clean themselves perfectly. It needs to have water in them to work though. We had the front AC inside shroud off so we added water with a small water bottle. If the vac gets clogged hold your finger on the outlet of the venturi and it will back pressure through the vac line and clear it up nicely. The other option is to get some good strong wire and snake it up the pipe, but make sure you file the end of the wire to a rounded point so you don't scratch the sides of the pipe. Cheers, and Happy Trails!
