Ok this is my last post on this subject as it is getting boring, and trying to give Daz good advice is like banging your head against a brick wall!!! Lots of the experienced window cleaners on here, and certainly the more successful ones are all telling you to forget trolley/backpacks etc and get yourself some proper kit ie a van mount!! We just don't want you to make the mistakes that we all made when starting out, which was to go for a trolley or backpack instead of a superior van mount.
Look around when your out and about and see what other established wfp'ers are using... nearly all of them are using a van mount because it is the easiest and quickest way to work. Nobody that I know who purchased a trolley in the early days is still using it. They really are the worst piece of wfp equipment you can buy!! An example of this would be a certain Mr Williams who posts on here, about 6 years ago I believe he went out and purchased himself a 125ltr omni-trolley, he put it in the back of his van and filled it up, I don't think he ever managed to get it out again, he gave up and simply strapped it down and used it as a van mount, but what a wate of money and space, he could of got himself a tank that would have taken up less space yet held 5 times that amount of water at a fraction of the cost!! But we all made mistakes back then in the early days of wfp, but you don't have to, Go out with an experienced wc who uses a van mount and see for yourself how easy and efficient they are to use.
I know your probably not going to listen, but remember this advice in 6 months time when you are taking your trolley to the local dump!!
