Black tank smell
Our new 2014 195bh had a 300 that leaked on our second trip.I called and they overnight end me a new one. Easy to install. Look for the serial number and call the maker of the toilet....they will tell you if you have one that falls in the list....she would not send me one the first time I called because it wasn't leaking yet. So it wasn't a " warranty " issue at that time. The next weekend we went camping and sure enough.....we got back home and I checked it..there was the standing " stuff" inside the bowl clam shell...I was so mad when I saw it. The dealer said "never heard of them leaking or having an issue". When I asked the service manager if they would give me credit for the brand new one I was getting in the mail and I would buy his best one he had in the dealer (ceramic, more sturdy)....he laughed and said "heck no, I don't want one of those on my shelf".
