Thanks everyone. I plan to use the switch quite often, so i probably want a switch over a fuse because i would assume the switch is designed to make and break contact more often?
It seems like most people on this site go to campgrounds. So their trailer is either stored or hooked to shore power. If you have solar without a disconnect that means your batteries are always fully charged and every morning get cooked at 14.4v. I still think that is what killed my deep cycle marine batteries premature. I read the trojan link many times over the last few years. It does not recommend a constant float on both sealed and flooded.
