    I've got a 2000 Ford f150 7700. How would I go about putting 2 batteries in it.

    More specifically, would 2 batteries solve this problem:

    First off, I thought this truck was already supposed to have a HD alternator in it. The battery that's in it is 1050 CCA and 2 years old. When I raise the plow, it dims all the truck lights. I'd like to lessen this effect.

    My truck does too. I really don't worry about it though and I start moving immediately. If all you are running is a plow and nothing excessive in regards to exterior warning lighting, I would not worry about it unless it really bothers you. Your money.
