Thanks, S. I appreciate that. It just wouldn't be worth my time, but thank you. I just need a controller now? Everyone here has been so nice, I am really excited about doing this project and I am so impressed with how willing people are to help. I plan on spending the weekend with my Dad doing this and that will be great bonding time. By that I mean I will end up watching his 70 year old Mexican frame do the whole thing and I will hand him tools while my mom tries to feed us. Good times!

I'd encourage you to have at least 60 watts per 100 amp-hours of battery bank. If I were in a "single battery" configuration, I'd probably do 150 watts of panel.
Why? Because the solar harvest from 60 is about 23 amp hours per day. Correspondingly 150 watts will garner about 58 amp-hours per day. Those numbers presuppose perfect conditions--so the 150 watts is a lot safer.
Thanks, Piano. Even though I will probably go with the 150 amp-hour battery, I think a single 100 watt panel is about the max I can afford and still manage in a reasonable manner within the space I have. I plan on either keeping it on the dashboard or mounting on surf racks when not in use (I have direct southern exposure in great San Diego sun) and then pulling it out and adjusting while at camp:
I am hoping that most of the juice will get replaced by the alternator/isolator while driving home and the panel is used only to top the bttery off and maintain. Is this sound reasoning? With a 100 watt panel I am now at budget limit. I will have to splurge for a controller. What do you think? Thanks!
