Our solution was a piece of thick foam to stand the aquaroll on and an old padded ski jacket. Remains of one are sewn flat over the arm hole and the hood sewn up, the other arm for the pipe, the elasticated cuff helps with protecting the coupling to the van.
There's a 'but'

But, inboard tank is by far the BEST. Anything you do with an outside the van aquaroll is a compromise where you have to hope it works. Digging the aquaroll out of snow or breaking off ice is never good on a freezing cold morning.
