i really hate plastic hoselock connectors, they allways leak or break or leak some more theyre rubbish,
does anyone have their hose on the inside, with a closeable outlet on the side or back or floor of the van, with like a roller guide so you can just pull it out and it comes out nice and smooth and you can have the doors locked? thats what i would do (if i had a van) probably in the floor at the back so that the hose comes out low for less of a trip hazard
