There are times when we are set up in a location without a dump station near by and hooking up and taking the Scamp
for a ride was the only solution to empty our gray and black water tanks. I came up with this answer. I bought an electric wheel chair hitch carrier from Harbor Freight, cut it down in both length and width to fit my 25 gallon blue tank. Hinged it to the hitch bar and cut down the ramp to act more like a tailgate. The hinges have removable pins to make stowing easier. This way it takes up little more room in the back of the truck than what the tank does by itself. I have a rear hitch on the back of the Scamp
and this rides there while traveling unless we have the bike rack on it. This was rated for 500 pound capacity with a bed of 47" X 27" it is now cut down to 25" X 36" and 25 gallons of water weighs less than half what the original rating was. I usually dump much less than that anyway.
