Water and Boondocking 101 Dumping Gary and Black water

I like your idea however a bit more capacity would be better.
You can accomplish essentially the same task using a 42 gallon Barker tote and a macerator pump.
I like your set up a can see the advantages but I'd like to see at least 80 gallon capacity.
That way it could carry both of my 40 gallon waste tanks.

The advantage of the blue boy is that it still can be gravity filled and towed or loaded into the truck and carried to the dump station when required.
