the two positive terminals are linked together and the negatives also so i guess that is hooked up in parallel ?

Yes, they are connected in parallel so it does not matter as long as you do + to + and - to -. There are also adaptors tat allow you to plug it in to your 7 prong trailer cord.

Recommend same terminals that the ones going in and out of the trailer are connected to. Should be + on one battery, - on the other battery. This helps ensure they charge more evenly.

Get the GP adaptor that plugs into your 7 pin plug. And get the 30' extension cord. Works slick!

I made a positive / negative pigtail using 50amp Anderson connectors and eyelet ends attached to the pos/neg terminals of the battery. I attached said connector to the side of the battery box for easy access. I have made a complete kit using two Renogy suitcase 100w panels and a Renogy 30a charge controller. All connections are made with the Anderson connectors allowing one or both panels to be used. I soldered all connections to ensure low voltage loss.

Our portable system came with soldered Anderson connectors. The stranded cable broke right at the end of the solder pretty quickly. I hope you have better luck. I replaced them all with MC4 crimped connections and haven't had any issues.

What cable are you using between the battery box and the solar panels?
