My Coach man Catalina has been stationary this past year and plan on using it at my maintenance shop.my problem is my waste tank was full and had not been emptied for a while so i called my local sept...
You don't have any buddies that could hookup to the trailer? That would be your best bet, driving with the tank3/4 full and multiple flushes. Just saying! It could take a half a dozen times to get it cleaned out. I bought a trailer years ago that had this same thing and it took a while to get it cleaned out and driving was the best thing I found to work. Good luck, Bill
