My 07 Scepter came with the sani-con and I've used it exclusively for the last 8 years with no problem. I bought an extra 25 foot hose from sani-con years ago and when I wanted to empty at home, I would just take off the end, attach the hose and pump into a clean out at home. Since the storage garage I use now has a dump station, I haven't used the extension for years. I don't leave the system connected to the CG sewer, just dump when necessary or before leaving so there is usually plenty of gray to flush with. I purchased a replacement impeller kit two years ago due to the age of the system, but never had a problem. The coach was in the shop for some mods last month, so I had them replace the impeller as a PM. I also do the gray to black flush as suggested in the sani-con literature and no problem in 8 years.
