I have a 55 gallon food grade closed lid blue plastic barrel that I take along to fill with fresh water. I sanitize it just like I sanitize the TT fresh water tank. I use a barrel siphon pump to drain the barrel into the fresh water tank. I have put a male hose connector onto the end of the siphon outlet hose in case I need to add additional water hose. Of course, the closer you get between the barrel and the fresh water tank, the better. This method keeps me from having to move the TT to fill with water or to make multiple trips to with smaller containers.
