I was looking forward to Vince giving a better explanation for this...........
I never liked trying to drag hoses out all the time . I take the pole and reel to the farthest point (I have nice light microbore hose) and run the hose back to the van and plug it in. I find that easier and quicker than trying to drag out a hose from the van. I couldn't make head nor tail of it. Could just be me? Maybe walking your reel to the furthest point is the way to go?
I think the OP is right anyway, its a waste of £500 to only work half a day
