"I have yet to visit Sam's for their option. "
I contacted Sam's Club in Reno, NV regarding the 232AH battery which they agreed to carry as they only carried the 220AH in stock. (Two week wait). I purchased four and the extra AH is not the only benefit as the plates are thicker so perhaps a longer lifespan. Johnson Controls makes the battery.
