Going to put my van mounted system into a shed at the bottom of my garden and use a trolley system from the back of my car . Any advice or pitfalls i should be aware off.
Reasons behind it
1/ Easier to keep stuff from freezing up in winter
2/ Running costs on 1 vehicle rather than 2
3/ Sick to death of winding hosepipe in and out in and out.
4/ Parking and access restrictions.
5/ Cost of fuel driving round with half a ton of water and all my kit in the back of
    a van.

I transfered all mine to a out building as so much easier just fills while im working, i now just fill with what I need for that day rather then always having 650 ltr in the back all the time, I think id get more fed up with a trolley then winding hose in all day, I only concentrate on getting work with easy parking and access.....

you only take enough water per day.  : I always have more than enough, will let you work out why

trolleys are a lot slower faffing about filling barrells loading car changing barrells lifting gear in and out at every job  running low on water half way thru a job having to go back to car and change barrells .......... nightmare

i set up once in the morning and pack up once when i go home

my pole is attached to the reel thru a port in the van then just lays on roof rack i only have to grab the pole of the roofrack then walk off

i wind the hose reel up with a cordless drill

i fill from a static system at home

add up time you will spend in a day faffing about and use it  to either clean more windows or do something else

ive seen guys with trolleys and im always half way round a house before they even get started

if i was you  id just get a ibc and atransfer pump and set yourself up a static system

a cordless drill and a 22mm deep reach socket will solve your hose windong issues
