This is NOT the kind of **** I need to be finding when I have a 6x6 project that I'm hoping to actually & properly start on this year. Have had enough delays as it is. After his description of how he did the tracks...is putting more pressure on the will to begin on a Bren Gun Carrier-ish build. I have a triple axle frame from a travel trailer. Made of 5x2in box tubing which would keep it light.
