Cheep easy way to insulate a shipping containers

Hi. I'm new here. I've just converted a shuttle bus into a ...''RV''... and moved into it a few weeks ago, even while converting and insulating it at the same time. Well, I just did my best in a very short time. So it's not that pretty inside, buy I insulated it almost completely. But after watching tons of videos on YT about converting small buses into RV, I found a video of a young couple living in a van in Canada explaining how they're dealing with the moisture problem during the winter. I learned that living in a bus (like a container) is totally different than living in a house. They installed 1 (or 2, I don't remember) 12 volt fans inside their van, and they ALSO always leave a window cracked open. So the moisture problem is taking cared of. That way, there's always an air exchange from inside with the outside air, so the moisture problem is taking cared of. So coming back to my situation, here I am, in my shuttle bus, the weather outside goes from -5 Celsius to up to -20 Celsius right now and I don't have any moisture problem. Unfortunatelly, the sun is very shy right now where I am, there were no sun for almost 2 weeks now... So I parked my shuttle bus in a camp ground with a 30 amps electric outlet, so I don't have the solar or stress problem. Before I learned that trick (a few weeks ago) I was closing the inside of my shuttle bus all tight from the outside with no air exchange between the inside with the outside air... Big problem, every morning, the water was glisening on the walls and dropping from the ceiling!!! So a container must be similar to a small (or a big) bus. So since your container is well insulated, leave some small gap(s) somewhere in your container so there can be air exchange with the oustside air. And use at least one 12 volt fan. I tried a small computer fan, but it was WAY too small, it was like not having a fan at all!!! Now I'm using a 6 inch fan, and it solved all my moisture problem. Only when I cook, then I really have to open (I mean crack) a few windows. I just thought that this could help with your moisture problem. Also, when I was looking what to buy for my solar system, I went with the 24 volt MPP Solar ''All in One'' that Will was talking about. But since there was almost no sun at all for the last 2 weeks here, that's why I decided to park my shuttle bus in a camp ground with the electricity included. In my case, all my solar pannels are still not installed right now, and also I unplugged my ''all in one'' system, and I recharge my battery bank with a small smart battery charger to maintain my batteries, but since I do have access to the grid power, I'm not really using my battery bank right now. But I'm here, still learning. There's just so much to learn. Anyway, I just hope this might help you.
