Solar Ready Camper Help!

Hello everyone,

I recently traded in my old travel trailer for a new one. This new one is "solar ready". I never dealt with solar panels before. All they said during the walk-through was buy a panel, plug it in, and go. Well reading so many reviews and other things, this isn't the case. I found out you need a charge control and then find the wires that go to the battery from the solar port on the side. No further directions were given and I can't figure it out for the life of me. My new trailer does not have a battery disconnect so the battery died and I want to keep it alive. Any help will be greatly appreciated.
