Solar trickle charger
Going into my first winter with my camper, I've been studying how my coach battery charges. I've been checking the voltage at the battery and then monitoring how it responds to running the generator ...

Thanks for all the great information--I will be studying/reading up for sure. I'm glad to know that the unit I found on Amazon is overpriced and won't suit my needs ... :-)
I also realized that my original post is unclear--I haven't allowed my battery to LOSE 70-80% of it's charge, it was STILL at 70-80% (so only 20-30% discharged). My battery is pretty easily accessible, and I've been using my handy voltmeter to check (waiting until at least 18-24 hours after any charging). Since I'm not really using the camper over the winter (I'm driving it for day trips only) I thought that this was the time to learn how the electrical system behaves.
I'm not sure which model MagnaTek converter I have--the manual is for "900 Series Converter/Battery Charger" and covers several actual model numbers. In the specifications, all of the listed model numbers give DC Output (volts) 12.0 min @ full load, 14.1 max. @ no load.
