Wow! Nice job! Thank you so much for the guidance. I talked to the dealer and was told the batteries that come with the camper are just what you started with and are part of the dealer prep. I asked if I could forgo those batteries and put in the lithium batteries and if that would reduce the dealer prep charge but got a no on that so I guess for now I’ll use that battery until I understand how everything works then get into making changes. Our camper which just got pushed back another month comes with 2 – 200 watt panels so I think I won’t have to do all of the mods you have done but just studying your pics is going to prove valuable I think. What I need to understand is how all of the system works since the solar will all be set up, hopefully?
