Best and safest space heater?
 

It's spring time and it's getting warmer so heaters are going to be going on sale soon. Wondering what everyone was using to warm their rigs in the winter? I'm in NC so we don't get that brutal of winters but I would like a little extra heat in the mornings and while going to sleep. I've got a good bag but being able to hang out in your rig outside your bag for a while is nice too..(What if it starts raining?). Optimally I would want something that has an auto cutoff.

Bumpppp

I have one of these and it works great. http://www.mrheater.com/product.aspx?catid=41&id=24
Has auto cut of. Best if you can crack a window so it has fresh air to use and then will stay on longer without shutting off.

I have one in my shop and I've used it in an ice fishing shack. I've also placed it below the oil pan of my diesel in super cold weather, far from electricity. Get the biggest one they have.
