Funny you should mention about the Aux tanks Len
But,,,,,,, if you wanted to,,,,,,,,,,, they are light enough to carry into a building,,,,,,,,,,,,then set up somewhere out of the way,,,,,,, fill Aux fresh water tank, connect Aux waste tank to Scorpion, and,,,,,, hey presto,,,,, an " inside" truckmount ( with 33 gal capacity)
