Changing battery Bank of 4 batteries--AGM?
I have 4 size 30 deep cycle flooded batteries that are about 6 years old. I want to change them before a big trip I'll be making this summer. I run a residential frig. I saw Cabelas has AGM marine bat...

I have the 2 older equivalents to their current x-900 in my boat for trolling (true deep cycle, group 31, 220RC). Going on year 6, with no issues. Great batteries. But I had to switch to AGM as acid splash out was an issue when getting pounded going over waves. Very hefty price for those.
