adding solar before trip

So, I'm a little late to the party. Guess you're probably already on vacation. Did you install your panel yet? We have the same camper. I'm removing my factory installed panel tomorrow (if weather holds) to pull new cable (current system has MC3 connectors and want to go with MC4 connectors) and install a second panel. Gave a quick eyeball last night and it does appear the solar enters with the sat ant, but can verify if need be. Regardless, you'll want to pull new cable. The MC3 cables are no longer UL listed as they can separate and all new panesl comes with MC4. You can get adapters (if, like me, you have panels with MC3 connectors), but that doesn't sound like that's your situation.
