I had a extra small trailer we really did not use, so I installed the transfer tank in it. I had thought about mounting it in the equipment trailer itself. But I figured that the real need was to have a tank at the house that could fill any of all 3 machines without having to drag them one at a time down to the fuel station. .and if I'm going somewhere with the. Aching on the trailer anyway, I can just pull in and top it off while its there. This set up will only make maybe 1 or 2 trips a year off the property to keep a fuel supply at the ready.
