I have one of these and really like it. Rather than stopping somewhere to dump, I can drive home and empty the tanks at my leisure. I use a garden hose and pump about 100 feet slightly uphill into my septic system clean out. I use non-formaldehyde chemicals in the black water tank. The pump usually gets a couple of breaks during the pumping out to avoid overheating.
