    Optima and Hellroaring is the only way to go!!
    The Optima will never leak acid and Hellroaring is nice and small for mounting and the customer service is OUTSTANDING!!
    Both of these products are not cheep but you will never need to rebuy so in the long run you save time and money!
    Go for it!!

    As for the actual mounting of the second battery, GM will sell you the driver side battery holder that is used on two battery diesel engines.

    I am currently using a Hellroaring Battery System, and Sears Range Handler. I went with the Range handlers because they have a super long free replacement and even longer proration. I don't know of any battery on the market that will offer a better warranty. Even if you were to cycle it too deep too often, just replace it. Optima will only offer 1 year.

    You could find a K5 that had a diesel in a junk-yard and pull out all the stuff for dual batteries. cables mounts and stuff. Or you could mount them under the passenger seat like in your hummer. just pull out the stuff from the m998a2
    You would need to switch the cables around so it was 12 volt and not 24 though. Pos to Pos and Neg to Neg is 12 pos to neg is 24

    Blazers Rule especially Diesels
