I determined that I'm woefully underpowered with that 100ah AGM battery. I looked at previous threads and some blog posts on the pros and...

    Simple solar for full-time living

    Hey everyone. I've been lurking around here for long enough and trying to do research in my conversion, but I think that an actual conversation with experienced Sprinter folks is the next step.
