in the process of turning my freedom trolley into a van mount(still need to use as a trolley for a few jobs),i set it all up today everything seems ok so far the only problem is the hose on the trolley which you normally place into a barrell,i put this in my tank but it doesn,t stop at the bottom and keeps moving up to halfway therefore not working when the water level gets under halfway,could do with something to way it down,how as anyone else solved this problem?cheers guys(sorry if i sound a bit stupid but not really much good at diy)
