Sprinter Source Book
This is a right of passage. Everyone starts here and works their way through the hundreds of options and choices. This will give you a broad overview of options and possibilities. Best $37 you'll spend. Read through it many times over. Take notes like a mad person so that you can reference it when it's time to purchase components. ***It might also be helpful to note preferences and choices.
Sprinter Source Forum
In the same vein we would never have finished our build without this incredible resource. The folks on it are generous with their wisdom and time. They seem to have endless patience for newbie questions. Just be polite and patient. Massive shoutout to "Autostaretx" who spent hours with me working on our electric layout and build.

We found that the folks who build boats know their stuff; they've mastered living in tiny spaces. Here is a massive resource for electricity-related build knowledge. There is a dedicated post about how to charge LiFePo4 batteries that blew my mind (light reading for a quiet Sunday afternoon).
Handy Bob's Solar
Foundational reading for your solar install. Learn everything you need to know about solar power here. We found that there is so much misinformation regarding solar; even people who claim to be professionals are sometimes poorly educated. There's a ton to learn, but trust me when I say it's worth your time to research this properly and do it right the first time. Bob is meticulous and has decades of experience.
