A Better 12-volt Diesel Heater In A Box?

So, here's my take on building a portable 12-volt diesel heater in a box. I know there are plenty of other similar videos out there, but I incorporated a number of good ideas from some of them to build mine. I built this one primarily to heat my Frabil Predator ice fishing pop-over that I have been modifying to use as a sleeper shanty. Check out the initial build on my channel and watch for an updated video where I show the additions and further mods to use as a pretty comfy sleeper shanty. However, the very compact size and portability of this heater build makes it great for use in any winter or cold weather camping anywhere including use with a roof-top tent when overlanding or a ground tent for posh glamping setups. Major credit and kudos to John McK 47 who has a fantastic series of YouTube videos on his channel that walks you through all you need to know about these units. All of the problems others have mentioned having with their diesel heater builds would have been avoided if they first watched all of John's great videos.
