I would like to set up my new van (Vauxhall Vivaro LWB) for reach & wash, i have a 1000 ltr tank & would appreciate any good idea's, links or sources with regard's to securing the tank. I had ratchet's in my old van (2 x 400 ltr tanks). This method was ok but would like a more professional alternative, as 1000ltr's is alot of weight to be carrying.
