i have a 2007 excursion 40e with four energizer GC2 house batteries that I need to replace. Are those the best bet for the money?

We recently replaced our 2 6-volt house batteries (Crown factory installed) with 2 Crown 6-volt C-145's.

They are 2 grades above the factory installed batteries @ $200.00 Canadian.

These are 6-volt Golf Cart Deep Cycle Batteries versus typical 12-volt Deep Cycle and I've been told by many people that Golf Cart Batteries handle significantly more charge/discharge cycles.

So far, everything works fine!
