We bought our new camper this year and love it but there have been a couple glitches (e bought a signiture ultralite Rockwood travel trailer). The main thing is that every trip the black tank seems to plug up right under the toilet. We have tried 3 different brands of tp and still have issues. Seems like the #2 goes down and creats a dam then the tp adds to it. After day 2 we have problems. Have any of you had a problem like this? We also tried running more water after each flush, say 3 or 4 seconds. The next is the black and grey tank gauges. After I dump they will keep reading 1/3 for a day, then bounce back and forth between empy and 1/3. I filled them both up about 1/2 with clear water and drove a bit to really clean them out but no luck. I hope to get it in next week but was hoping for guidance. The only good thing is it pushed me off the edge with buying the extended warranty! $1683 that covers pretty much everything for 7 yrs suddenly doesn't seem so bad. Thanks so much for your time.
