I had my reels fixed to the side doors of my van also, as i find it better, well i prefer to work this way. Mine are fixed to the floor, but Clive, i would love to see your roof mounted reel version if possible? I also have a 3rd outlet at the back behind the bumper for another hose reel for a 3rd person if and when it is needed. I didnt have the reels at the back because i wanted more room to carry equipment, and i also have space in-between the reels at the side, where a gutter vac sits nicely. I like Clive, have an 800 litre skid tank, again this works out well to carry the diesel heater, pumps ect on the platform where i had a cage made up, and can carry ladders and secure them on top of the tank as i dont carry ladders on the roof of the van. I used to work with the reels at the back, lifting in and out, but when i got a new van and system, i like Clive thought this would be a better way of working, and i much prefer working this way. I can still lock the back of the van if needed, i just close the door up on the microbore.
