Looking at setting up running of a hose reel instead of a trolley for some houses. I haven't got the room in this van for both, and I still want to run with a trolley in the back. So I have plummed in a port on the van, this is a hoselock connecting (under van ports) So I am looking at a small piece of hose to join from port to a hose reel.... I would like some help on the following. What hose? What size 6mm or 8mm. What is the difference. I know size lol. And what sort of hose reel please? Thanks guys. Budget is £100 for hose £100 reel. Thanks.
