I have a Coachman motorhome and sometimes my shower drain leaks. I use the motorhome half the year and we both take showers most days. After a while my drain leaks around the flange in the shower pan. I take it apart and use plumbers putty, tighten it up again and it is ok for a while. The puitty works out or gets old after several months. Has anyone used any other stuff (silicone, etc) under the lip of the drain where it meets the shower pan? Ideas?
I wouldn't use silicone. Latex or siliconized latex will work much better and clean up nicer. I'm a plumber and I never use putty on a plastic drain because you can't get the spud tight enough without breaking the flange. I use latex for this all of the time

Also the way they Install these showers allows Movement in the Pan area,which adds to the problem! Some Pans are Hanging in Mid Air! Youroo!! These Pics. are after (Bridging) was placed to support area removed under pan at the Factory to fit Trap!
Since I am living in my motorhome in Arizona right now, I have not had a chance to fix the drain. I did get some silicone latex in a tube and will do it next week. And I already braced the bottom of the pan because of the flexing. Let you all know what happens.
I blocked up under the shower pan in our last RV, much like Youroo shows and I also found a rubber 'P' trap and replaced the rigid one with it, so it wasn't stressing the piping. Never had another leak there as long as we owned the unit.

Gotta go campin!
Mine broke the pipe, so I braced it and used heaver wall tubing. This happened soon after we had the unit and we were away. Naturally on a Sunday, took it apart, went to Lowes, got the parts and has been fine since.
