Have you considered installing a blade type battery disconnect on the negative post of the engine battery?

the problem with doing that is losing the data that the various CPU's have gathered about driving habits, shift points, etc., not to mention reloading the radio and resetting all of the configs if you have a glass dash. Our DP was good for about 3 weeks before dead battery time, so thats when I started adding Solar

if you plugged solar power into dash DC outlet (often used to charge cell phone), would that charge the chassis batt, or does the recepticle flow both ways?/

if so, i wonder if a windshield heat reflector has ever been made of a solar panel that plugs into the DC recepticle.

Something that small really can't keep up. That's what I read on here back in 2007 and they were right. I had a little 15w panel on the roof and it proved useless. I started with a 100w panel just to maintain the batteries, and Santa jammed another one in my stocking the following years, now 1/2kw.

If you are trying to charge both house and chassis, I think you need to start at 100W
