Dual Alternators

[bobsals]

A friend of mine is ordering a new 2013 F-350 with the 6.7. He is trying to decide if ordering it with dual alternators is a good idea or not and asked me to post the question here. Is there any disadvantages to having the dual alternators? I'm not really sure why he wants them, the only thing he tows is a 30' fifth wheel camper. He would just want to get opinions of the guys that are into their Superdutys day in and day out.
A question I have is what kind of equipment would warrant the dual alternators?

Thanks

I also ordered them just for future upgrades if wanted and less wear on one. I pull a 40ft fifth wheel.

They are useful if your going to be using alot of things that draw power. Like if you had a snowplow, Baja lights, or something of that nature. If he isn't doing any of that I'd just stick with the single.

Agreed, stick to the single. One less part to go bad.

OP, just order the extra heavy duty alternator instead of both. if he is buying a lariat or above they come standard now.

I ordered the HD alternator on mine. I felt that I really wouldn't draw enough power to require 2 (though I do have the supplemental cab heater), and 2 may offer more parasitic losses (more fuel burned?).

I ordered my 05 with dual alts. I had a slip in camper and a boat I towed. Used the truck charging system to charge the boat and camper batteries, boat through a separate wire I added. Only down side I've seen is slightly higher maintenance costs.

Thanks for the great replies guys, I'll pass on the info.

On the Platinum I think they make you get dual with a snow plow package. And 2 alts would definitely draw more engine power to run.

I ordered both of my trucks with the HD Alternator.
