Oh how I love my Sewer Solutions hose setup. 20' of 1-1/2" hose rolls up like a garden hose, can run over it with the truck (no leak or damage), easy to create a trap in the line, washes itself with usage and it will flush uphill about 1 to 2' in 20' of length. I store this in a small plastic bin with the various fittings, and smile every time I use it. I have additional pvc pipe for those odd times you need more like 30'to reach the sewer like in Mexico. I was the "come to" person for flushing tanks while on safari down there in those odd setups.
