The only tricky part to locate locally was the British male thread to female NPT (found eventually on Amazon). The heater unit is mounted to the side of the toolbox using four angle brackets ($2 each at Lowes), some 1/4 screws & lock nuts. The diameter of the vents on the side of the unit (not the exhaust/intake on the bottom) is 60mm, so I ended up having to rig it to two 2 1/4” to 4” vent couplings. I lined these with foil tape, not sure how the plastic will take the heat just yet. The tricky let’s of the build are lining up the holes to drill for the mounting screws & the intake/out vents. Once it’s all assembled, it still leaves enough room in the box for a 12’ propane supply hose & regulator. They recommend using a 2-stage reg, might change out later. Let me know if you have any questions!
