[Bungle]

I did WFP out of my car years ago. One thing I would recommend is for anyone going down this route take a DI vessel out with you. I used to ask customers if I could use their outside tap (of course) and fill a barrel whilst cleaning their house.

£605 for a sack truck, barrel, pump & controller lol.

The stainless steel version is £1075 !
