    Ford almost always buts the second battery on the opposite side of the engine compartment. You may have to remount the air filter or the vacuum canisters.

    I agree with Grumpy, both of my last two F250 (diesel) have had the two batteries mounted right behind the radiator support on both sides of the radiator with the connecting positive cable routed across the top of the radiator support in front of the radiator.

    Put er in the bed of the truck. Get some cables made up and route them to it. Great for boosting other equipment. Or a link in charging up the battery on yer sander.

    why does everyone put a second battery in their trucks? ive been plowing for 17 years and the only trucks with multiple were diesels, never had a problem were i thought they were needed.

    Our Current 87 F-250 gasser has the stock battery on the passengers behind the radiator support.
    The secondary battery would go in the same location on the drivers side and mounts to the inner fender.
    You will need to relocate the overflow/washer fluid tank.
    If you are installing the additional battery for capacity, consider installing a battery isolation module.
    What is your alternator rated for??

    I think it is only rated at 75 amp.... Isolation module?? how does it work?? I know a bigger alt will help, However I would have do do some upgrading to the factory wiring I think

    When I owned my 91 F250, I went with the easiest way I could think of. Some of you might laugh, but I used it this way for years.

    I made a removable holder mounted right to the plow frame. Ran some 1 gauge wire with a quick disconnect.

    As the name implies, the isolation module isolates the primary battery from the aux battery.
    I would upgrade your alternator first.
