i need a 50 liter or more wfp trolley as over the last few months ive got a lot more customers and have started to wfp tops rather than trad full house this is due to lack time and also so awkward windows that i need to use the pole on, and get fed up of switching about from ladders to wfp the reason why i want a 50l one is beacuse i have big runs of terrace houses and end up spending to much time walking back to van to get more barrels and cant use a static systeme as i would need a 500ft hose and also im near the high street so parking isnt brilliant thanks
