    No. I believe that the 2nd battery is an option (TP2). It is actually an auxilary battery designed for uses such as campers, inverters and plows. The 2nd battery is not in series with the primary battery as it is ordered from the factory.

    2 batteries is an option. There are 2 duel battery options. Look on your RPO sheet for the following codes.
    The tp2 option is the 2 hooked in series (like come on the dmax).
    The 8B0 option is the isolated hookup.
    The tp2 is good for plowing and other uses that need a high draw when the engine is running.
    The 8B0 is good for uses when the engine is off like campers, inverters,etc. because you only draw off that battery and always will have the other to start.

    It is an option on your truck. You can get the tray and mounting stuff from GM. It goes on top of the fender on the passanger side back towards the fire wall. You need to remove the fender brace on that side. Seen many 99-06 6L HDs with the dual battery option.
