A good brand of AGM is more resistant to the cold weather blues than a flooded battery.
Flooded batteries typically use 1.275 gravity acid -- AGM uses 1.300 which I used for Arctic blend flooded batteries. A hundred ampere draw off an 8'D at 30F should reduce voltage to around 12.1 from 100% charged 12.8
Double the batteries to (2) and you will see even higher voltage at work.
Four batteries will deliver 2 Kw for a half hour without breathing hard. Peukert is of course at work but when the load is reduced voltage will rise again.
Washington State was home base for Trace which means the grand uncle to Outback. Call Outback and see whom they recommend in your area.
