The hose isn't heavy at all, it's not the hose everyone think it is.
It's pretty obvious the coiled hose is not the standard hozelock type coiled hose. It's also pretty obvious that if you've spent that much time and trouble to organise your van the way you have, you'd hardly be using hose that was so heavy it's almost impossible to use when window cleaning wfp.
I was impressed by your van. I have a Transit Connect and everything, while all very functional, is just stuffed in in a sort of semi organised fashion it isn't well thought out. Now though, having seen that video, I'm going to think it all through over the next few weeks and really work out where everything needs to go and make all the modifications to make working life easier.
Also, I was incredibly impressed by your portable pump. That is a real gem of an idea. Thanks for that.
