Been using one for 5-6 years, dump at home after a trip.
Lucky that the generator is close by the dump connection and I can hook up the pump wires there.
I have a pair of long needle nose pliers to remove any debris left over in the impeller and a HD 3/4" hose to connect to the "clean out trap" on the house. I made an adaptor to screw into the 1 1/2" clean out fitting (1 1/2" male pipe to 3/4" female pipe) and then a 3/4" pipe thread to hose connector.
Works great and no trips to some pretty gross dump stations
