I started with a trolly (sack truck) hitched to the back of an estate, used this for about two years, found the best way to use it was to leeve it attached to the vehicle, tried several types of reel, small ones ( from places like B&Q)worked fine (need a little Ingenuity to fix it to trolly) As the car was on its last legs I eventually attached the hose reel to the boot lid and put the water containers / battery / and water pump inside vehicle looked odd but worked great.
