The battery shop I go to recommends a wet deep cycle battery over the AGM since the battery location is outside. Seems like there is no concensus from forum members on prior posts regarding AGM vs wet. Although AGMs seem to prevail for some reason.
I have no other needs for power other than the fridge.
Sounds like a 125watt panel will give me plenty of juice for my needs.

I'm sure there is a discussion on battery types (with links) somewhere on this site.
Wet cell batteries take longer to charge, need to be monitored to keep the water up, and suffer from off gassing during high amp charges. Heat affects them more.
AGM's can be more expensive, generally weigh more, and are subject to failure if the voltage drops below 10.2 volts. I think Optima batteries weigh a little more than a wet cell counter part.
I plan to install a bypass switch ASAP just incase the battery separator fails as it has in the past. I still prefer the battery separator for normal operation.
Depending on your load, a small extra battery might not suit your needs. I find 2 4-D's work for me but the single 4-D was at the limit. Your mileage might vary. So research the archives here and on the owners group.
Good luck on your quest.
