Dual Batteries
Building a new Superduty, XLT, 6.2, 3.73 gears. Build Site, "Medium Duty Battery", $210 option, reasonable, IMO. Dual batteries, worth the money? Or just something else stuffed in the engine compartment? Have not been able to see one on any lots.

This depends entirely on the end user. If you intend on using the truck with any type of electrical accessories that have either a high nominal current load, high inrush current, or simply extended duration of use, then it is definitely worth getting the dual setup. Things like snow plows and winches are perfect examples of accessories that benefit from the dual battery setup. I would also add the Extra Heavy Duty Alternator option for $85 if you get the dual batteries, just cheap insurance IMO. Again, it all depends on what you intend to use the truck for; if you will never have any extra electrical accessories, there is no reason to add the dual battery option.

I wish I had the dual batteries for camping. Simply because every time I open a truck door, every marker light on the truck and camper comes on and stays on for about 30 seconds. Over the course of a week or two, that's a lot of juice. My work around, if we've been in and out of the cab a lot, is to start the truck very few days.

It's a slide-in camper, so the connector is hidden, and I don't want to risk forgetting to plug in again. Besides, the truck marker lights alone draw 11 amps.

I ordered the dual battery setup along with the XHD alternator. Got it mainly so down the road I wouldn't be saying: "I wish I would have ordered it". Either way I go, there will be plenty of juice to power my future add-ons.

10/4 on "I wish had ordered Dual Batteries". For $210 its a no brainer. I know at the very least, I will have a plow on it.

It would be nice to have dual batteries, as I've got the plow and plenty of exterior lighting, but even while monitoring voltage with FORScan, the plow is a minimal draw. All my auxiliary lighting is LED. Plus I have the "extra extra heavy duty alternator" which helps. Too bad it's so hard to find a dual battery setup on a dealers lot.

You can always add the dual battery setup if you want it. OEM or aftermarket is doable. It will cost a bit more than ordering from Ford up front. Here is a thread about it: OEM Dual Battery
