Ok, after a few days of deliberation (felt like weeks!) and reading loads of info on here I have decided to purchase the trolley system from Pure Freedom.
Probably the 50 litre version. I believe if the business goes well then I can upgrade to van mount, but from what I have read it look slike this system can be used as a van mount as well
It comes with all the kit I believe - think I might need another pole?
I haven't got a clue how to make the water - cant be that difficult, right?
Just now wondering whether I should buy the little gutter cleaner as well for £220?
Thanks everyone for all the help and guidence so far
Lets hope I dont dither as much over a small van!
