    Welcome 680, 5 batteries sounds like a lot. You should probably start a new topic with your questions so more people will see it.

    If you drive a lot and dont key a lot you'll be ok. Your stopping distance will be adversely affect by all that weight.

    Do you really need a 2x8 in the mobile?

    The truth is you can easily run a 2X8 with the right additional alternator and regulator, without a single battery inline! Up to 21 transistors have been run on one 250 amp alternator with nothing more than a lightweight capacitor bank to filter out the ripple. The regulator is modified to energize the field only when keyed so voltage is removed when the load is. The regulator also uses a diode to pulse the field from the stock 12 volt source in order to start the alternators magnetic field under load since no battery voltage would be present to do that.
