I'm planning to start cutting plywood tonight! I took a little time off from projects (a week or so) and now it's time to get back into it!
I've been kicking around the power needs. I don't have a fully set amount of power draws at this time except for my Engel MT 35 refrigerator. I only expect a small amount of LED lighting and phone charging beyond that. I plan to have an onboard charger with a shore power hookup so I can plug in when I'm at home and in certain locations on the road - to keep the battery/batteries happy. I don't really want to do solar as it seems like overkill for our camper. Let's talk batteries:
Group 31 Marine: odyssey batteries in this class require really high current (14+) to properly charge which makes them a bit of a hassle to take care of properly. Especially since they don't offer or endorse a charger for that battery at this point. Other marine group 31 batteries are an option possibly.
Lifeline 4D battery: This one is intriguing to me. It's about the same cost and amp hour rating (200ah) as two group 31 batteries but in a slightly better package size for my particular camper. It doesn't appear that they are as finicky about charging in that any good 3 stage charger will work. Their charge needs are within the rating of my alternator too, which is a huge bonus over the odyssey group 31.
We'll likely start the truck and drive around every day as we're wanderers, however, I'd like to be able to stay maybe two days in one spot without starting the truck at all while still running the fridge and some lighting and charging phones.
I'm not an electrical engineer or even pretend to understand, fully, what I read about this subject so I'm open to any and all discussion on my evolving plans. I know there are tons of threads on batteries and I've worked on reading up about this stuff but there is SO much info and everyone has an opinion supported by what seems like sound data. I'm likely to just go with my gut, keep it really simple, and see how it goes.
And, some notes on solar and our current leaning toward not having any:
1. We have surfboards and SUPs that we will carry on the roof on a decent amount of our journeys. They will block the panels completely for most of the trips those toys are taken on.
2. We live in the PNW so it's not overly sunny here most of the year. Plus, we have a lot of trees which make it hard to keep panels fully in the sun.
3. I don't shy away from narrow and overgrown trails. Panels are another thing to get damaged. I know this 'excuse' is thin as many people do what I do with panels onboard with no issues, but it is still a concern.
With a properly sized battery bank that I can properly charge with the alternator on the truck and shore power when I'm CGs or at home, I think going without solar will be okay. I can always add a suitcase system later if necessary, anyway. My camper isn't complex so reworking the wiring/electrical system won't be too daunting.
