Black water emptying in a tote.

[5ERSTEVE]

So I am loving my new Prime Time 297RSK. It's parked semi permanent for now at a cpsite. The dump station is about 400 feet away so I have been using a 42 gallon tote to empty the black tank. The tote has a top mounted opening for the 3 inch and the trailer has a pretty low outlet.. consequently I end up lifting and lowering the 3inch hose for the last 20 gallons or so to get the tank empty. Was looking at getting a Flo jet 18555000a to solve the problem and get rid of the 3in hose using an adapter on the tote to go from 3inch to 3/4.
Any suggestions or thoughts about this or another way? The lifting/lowering of the 3inch hose has wore one out already....not a leak I enjoyed!
