block heater?

Would a block heater and battery heater be worth the money for the winter? Anyone use them? $80 for both is cheap on ebay, or to me it is. I am asking if anyone has any experience with these in the 4.0. I've read that battery power drops 30-50% in the freezing cold and don't want to go through that hassle.

You don't need one in NC. It does not get cold enough. If your battery is in good shape, you won't have any problems.

Lower radiator hose engine warmers work pretty good if installed correctly. I use them on a few of my rigs. Again, they must be installed correctly.

I have one on my 99 TJ, 4.0, and since it spends most nights in the garage in winter I don't use it much. But growing up in Montana they were a must, particularly when the weather in winter was more "normal" each year (-35 degrees F) and if you car/truck stayed outside. I also just installed a new Sears Platinum battery so I'm not worried about any decline in cranking power. It's nice to know it's there, just in case.

Heck yeah, and if you leave your ducts in the defrost position when you shut your rig off and plug it in at night. The small amount of radiant heat flowing thru the heater core will keep the bottom half of your windshield defrosted. The one on my small truck keeps the coolant at 80-100 degrees in COLD weather.
