I'm guessing the OP doesn't need a discussion as to the esoteric value of different types of batteries. He hasn't posted that he runs any significant loads that would dictate a certain type or amount of capacity.
IMO, 2 x 6v GC2 batteries will be the best solution. More durable to typical RV owner abuse and longevity will be the best for the least price.
We are all guessing about the OP's loads, true. But there's no need to make any assumptions. It's really rather simple.
And knowing the differences/limitations between "starting", "marine/RV" and true deep cycle batteries can be quite useful. It's not that "esoteric".
So if there's no heavy loads, no inverter involved, then your recommendation is the same as mine: 2 x 6v GC2 batteries. Perhaps the Trojan T-105s.
But, on the other hand: My trailer came with two GC2s which can barely handle my 1000W inverter. If I had been aware of the differences, I would have ordered two Marine/RVs instead. Perhaps the Trojan SCS225.
