Here is my issue: years ago my wife and I were right into winter camping. We'd go out in temps that went right down into ranges where the vehicles might start having problems starting the next day and enjoy ourselves mightily. It goes without saying that for -20~30 C that you have the right gear. It goes without saying that the blood of a 35 year old runs a little hotter than that of a 55 year old too.
Now I don't want or need a full blown winterized RV. I am thinking I would LOVE to be able to do, say, -15~20 C at night and still stay warm - in the back of my little Toyota truck. Here's the problem with that though: propane heat scares the shit out of me. I do not want to be in the back of my truck sleeping with one of those on for fear that I'll wake up dead the next morn. Also, at those temps, propane starts misbehaving. Pentane does too. So, I've been stuck with the rotten wood slowly smoldering between my ears as I think about heat for my mobile ultra-mini camp rig... and then I saw this:
Now, a newbie to wood heat would think that little cub would be just perfect for small truck and canopy camper like me. But: that thing, if I am not mistaken - will belt out enough heat when it gets going to fry me. A lot of folks that have never experienced wood heat aren't really up to speed about how efficient it is. But I think I might be able to squeeze this into my truck bed for cold nights.
It would be cramped as hell, but remember, I only need to get out for a night or two on weekends. The install looks like it might be fairly simple and straightforward too. It's made so the airflow can be throttled so a guy wouldn't need to be running it at full blast all the time. I just need something to keep the condensation and frost at bay during the night. Using the reflective surfaces I think I can safely run it at night. It would just be me... if I had to bring the wife and dogs the space just wouldn't be there.
