block heater, external power supply

Hello I am looking to buy a 2011 F350 diesel. This would be my first diesel so I am trying to educate my self as much as possible. The one thing I am thinking I might have an issue with is plugging in the block heater at night. I live in a apartment complex and can't run an extension cord to the truck. Sometimes I am not parked anywhere near my apartment.

My question is it possible to power it from either another car battery say in the bed of the truck or a really good battery jump pack? I am thinking a marine batter with a dc->ac conversion running from the bed of the truck would do the trick.

Any input would be greatly appreciated. Thank.

Not likely from a battery, the heater draws 900 watts. This would kill most large batteries in minutes, and wouldn't have a measurable benefit.

How cold does it get where you live? You only need the block heater below -10 F.

I wouldn't worry about it if it were me. I've started mine at -11 before after sitting for three days. It fired right up without any problems, but it did give me a message to wait 30 seconds before driving.

If you really needed to plug it in you would need a generator to power the heater.

This worried me because the weather here in NY varies so much. Not being able to get to work would suck. Maybe I should think about a gas truck.

Snake,

I think the larger question is whether or not you need a diesel engine. Do you need that much power? Do you think they're just cool and worth it to pay an extra $8,000? If ambient temps around you occasionally get into the minus teens, you won't have a problem starting the truck even without a block heater.

yeah we are a construction company, constantly towing dump carts and materials etc. Our average low is 15F. This week this cold snap has put us at -5 for 4 nights in a row. So you guys think I will be fine with cold starts in the teens for all of january February?

interesting this from ford say -10F like you guys said. It is EXTREMELY rare to get that cold here. And if I knew it was going to be that cold I could park the truck at the shop and plug it in there since it is so rare.

The manual says to use a block heater when temps are below -10. Many have started fine without the heater in the temps you are describing but you are in that gray area.

Ford's recommendation of plugging in at -10 is coming from a guaranteed easy start/convenience standpoint. -10 is not the magic number where the truck will no longer start. At 5* F my 6.7 starts better and easier than my 6.0 did at 30* F. Basically as long as you have good batteries and the truck is run daily, I wouldn't be afraid of -20* starts without plugging it in. Between the common rail injection and the new improved glow plug system, these things are an absolute gem on cold starts compared to earlier models.
