I have a backpack and seem to be getting on great with it. 
I use it on nearly all customers now. 
I am looking at getting an Escort van and planning at some stage fitting a system into it so i dont have to keep going home to re-fill my containers.
Can anyone tell me what size Water Tank i can put in it in reference to its weight when full.
Also is it fairly simple to build your own van system as some can be quite expensive?
