Montana high country 338DB needs more batteries

I need to replace the 1 battery that came in my fifth wheel and add a little more capacity. I'm thinking about 2 Trojan 6V or 1 or 2 Trojan AGM batteries. Any suggestions? We camp with hookups most...

I'm not sure yet which route I will go, but I'll need another battery box. Can I purchase one and splice the vents in to the existing one? I'd rather not cut another hole in the fifth wheel if I don't have to.
