Sub Zero Diesel Heater Set Up (VEVOR)

I have done quite a few set ups with the diesel heaters and was working on something that would work in Manitoba toughest climate. I believe this is the smallest insulated box I could make and so far it has worked extremally well. The heater I was using is the Vevor 8Kw and can be found on amazon. All of my power sources come from Dakota Lithium and the website is listed below. Dakota Lithium https://dakotalithium.com Feel free to put a comment below if you have any questions.
