I'm a huge Interstate user but you might consider Deka Batteries. Most are USA made.
Lowes Lumber seems to be a nationwide Deka seller.
Is there a less expense seller of Deka?
Marine versus Automotive?
If you have room under the hood
is a Marine rated Deka battery of adequate CCA
likely to last longer
in the road vibration environment of automotive service than
the generally cheaper auto service rated batteries?
I wish that a 1000 owner group of Cummins Ram owners
with dual batteries under the hood
would volunteer to do a long term test
with both a marine and automotive rated battery in parallel service.
