I joined a few months ago but didn't realize that I had to do this step before I could post. I'm in the process of converting my van into a camper but the going is slow - mainly because there are so many opinions for insulation & solar. My primary concern at the moment is whether I should go with a traditional solar charge controller or CTEK D250s & Smartpass. I've been leaning toward the CTEK products so that I could charge off my alternator too. I like that option over a solenoid type battery isolator but that's more because I'm ignorant. I'd love to know what equipment other folks are using to charge from their alternator.
