Hello Scampers, just seeing if anyone else has encountered this problem. Last weekend when we were camping my wife was showering in our 13' Scamp with the shower/toilet combo. I noticed water was dripping underneath the Scamp.  Upon closer inspection I could see the water was escaping the Scamp right next to the black water drain underneath the trailer. I called the Scamp service line and they said there is a wax ring under the black water tank to keep the water from escaping the Scamp. Therefore the wax ring must be compromised allowing the water to escape and not run down to the shower drain.  They advised rather than attempt to remove the toilet and black water tank to replace the wax ring, to instead caulk all around the bottom of the black water tank. I'm pretty handy most of the time however the Scamp employee is afraid of me opening another can of worms removing and re-installing the black tank/toilet. Hopefully this makes sense and any advice would be highly appreciated. Unfortunately I cannot find any diagrams, pictures or information on this topic.  Thanks all!!
