Gav, if you dont mind them on the floor, but dont want them flying about, i have a strip of plywood, that goes the whole width of the van and is wide enough for the hose reel to sit on, the reel is secured to the plywood by 4 22mm pipe clips that have a tap that snaps over so the reel cant come out. This holds the reel in place, but you can also easily remove it by unclipping the taps and removing the plywood from the van.
