I have solar panels but with it inside they will just be idle.
Do I do anything with the inverter?
Do this procedure also keep the chassis battery charged?
Looking for comments.
I assume you mean 120 volt service above and your "splitter" is actually is actually a 15 amp to 30 amp adapter plug.
Not many Transit-based Crossfits out there, but it seems many more Transit "b's" are on the way from various manufacturers. As far as your specific model, leaving the inverter "off" is best, so long as the charger portion will keep the batteries at a proper float voltage. This is an important step you need to verify by past observation, documentation, or a call to Coachmen.
Again, not familiar with your model, but you're in Minnesota so you'll need to properly winterize the water pipes and tanks by draining and blowing out and/or adding the proper amount of RV antifreeze.
