Looks good, and a great idea, John!!
At first glance, I thought it was the vac side of the MYTEE Truck Mount.
Hmmm not a bad idea there. A manifold of some kind on the intake side to connect them, and a direct water hookup to the customer's hot water.
A generator to power the air movers, and there's yer Truck Mount.
Odin will be jealous.
