U're getting radical with your gadgets lately, aren't U ?
I found that the little buddy puts out way too much heat. My plan is to leave the little buddy back at the ranch and go with a Stansport double mantle propane lantern that will provide but heat and light and can be adjusted to provide just a few hundred BTUs of heat.
If you one night can't avoid being in true cold (where was that shot of sleet on your van???), I think you'd long for the Mr. Heater. It can warm up a van so much faster and better. I have wondered for my own van about the smaller Mr. Heater that sits atop the propane canister. It looked too unstable. I stayed too long up in MT last fall and fell in love with the Buddy. LOL
Now the heater has decided to act properly. One would think it was a computer infested with malware instead of a very simple mechanical device.
