What's the best battery setup for 200w solar?

My Lance has (2) 100w panels and a 30a controller. It has a single battery compartment and after sitting covered since fall, the battery is dead of course after I pulled out t out to get ready for summer. I'm either going to replace with a single AGM or some tell me to go with two 6v golf cart batts?
I have 2 AGM's in my travel trailer with 400w on the roof and it does great but the Lance is more compact with one battery compartment.

So two 6v or 1 AGM?

    Battery box on the Lance is a single. Pretty much answered my own question. I'll go with a large AGM for now. Maybe add another to a storage area later if needed. I've got a Honda 2000 to make it work as needed.

    Remember that AGM's can be laid on their side, or at an angle with zero adverse effect. You can also remove the slide tray to create more room or add a torqlift hidden power battery box on the truck frame under the bed. I was able to stuff two group 31 AGM's into my Lance 1055 to go along with my 200 watts of solar

    Have you determined your daily energy use? Get batts of at least four times your daily use. Generally 200 solar watts can recharge a 200 amp battery bank. I use 50 to 65 amps per day and have 300 solar watts recharging T125s at 240. Usually full by noon. Works great.

    So the 'single' battery compartment will hold 2 batteries? I would not choose to go flooded battery over AGM. Agm's are just too nice and maintenance free.
