Did you take pictures, or better yet, videos?
I’m sure that I can do it, but I’m a little freaked out over putting more holes in my bus. (You should have seen me when I started drilling holes into my roof to secure my solar panels lol )
I recently bought two Warmtoo 8K heaters - one will be for the bedroom and the other for the front, and I'll start installing the rear one soon. Because it's 25 feet or more from the bus's fuel tank, the little metering pump probably won't suck fuel that far to the heater, so I also bought a pair of Amarine gear pumps to push fuel from the bus's tank to both heaters' plastic 10-liter day tanks. Getting the rear heater's exhaust safely out of the bus without introducing excessive backpressure and without having an ugly eyesore of an exhaust pipe was another challenge. I bought a 1.5" polished stainless deckfill for boats, and that will attach to the outside wall with a length of 1.25" stainless pipe inside it as the actual exhaust pipe; the heater's corrugated exhaust flexpipe will then connect to the stainless pipe to make a neat installation, and the marine deckfill is the same as what I used for my two water tanks' gravity fill inlets. No cheap plastic RV crap for me! This will be a fun project, one of the few I can do while my usual local suppliers are closed during this pandemic.
I've also just ordered a Pioneer 12K minisplit A/C with heatpump, and my plan is to use that for heat whenever my solar panels are producing enough power in winter to run it, so maybe the diesel air heaters won't get much use; however, it's always good to have two ways to stay warm, so if one craps out then you're not totally SOL.
There's no need to freak out about making holes in the roof. I drilled 76 holes in my roof for my solar panels and walkway, and they're sealed well so they won't ever leak or cause problems.
