thank you, that guide is extremely helpful already. just scrolling down two inches, found a supremely simple and helpful diagram of an rv electric setup. just having that alone helps clarify and connect the dots of what I've been reading already. now I know what order everything goes in, and all of the equipment needed for the most part.
so now, I plan. will be kinda tough, and will only do a general design like - where walls are, appliances, seating, etc so I can (roughly) have an idea of where to position my wiring. thank you guys big help already!
tackling finishing removing caulking(so many ing's) this weekend and hopefully ordering everything I need for my electrical.
