I bought a system thru CW a few years ago that has worked great. I've used it for 1 1/2 years full time and never had a problem, uses no electricity, no motors to wear out either. It is a water-powered system that uses a jet of water to break up the sewage and pump it down a garden-hose sized line to the hookup. No more large hoses to haul around AND it will pump uphill. I had to pump 100 ft with a 2 foot head for most of that 1 1/2 years. Bought the extra 10 feet of hose and connected it to 1 inch pvc for that long run. Sure is easy, less bulk, and the only drawback is that it takes a few minutes longer to dump. It's called Sewer Solution, item 16617, $95, and I suggest getting the 10ft extension.
