Thanks, guys. For now, I'm sticking with my OEM charge controller, but plan on adding a 100w portable solar charger to give me an extra day or two. Biggest continuous draw on this new rig will be the fridge fans, since it's in a slideout. This does concern me and I really don't want to schlep along a genny for a 4-day 'docker, nor do I want to fire up the Duramax for a couple hours a day. =Nobody= would be happy with me for that! :B As I said, I'd =love= to build a Li battery pack, but need to win the lottery, first.
FWIW, my cousin's build blog on their bus is:
www.beginningfromthismorning.com. Lots and lots of details and videos.
