I recon the Tims fixed hose reel is better even although he has to open his back doors to wind the hose back in.
Very undecided about the poles being attached to the outside of the van though. Nice idea, but theft of the pole not used is very possible and probably inviting.
I also don't like the idea of a couple of holes in the side of the van to wind the hose reels in as has been commented on. Where did he store the cranking handle as I didn't notice?
