My truck does fine on cold weather.
Make sure you get your block heater hooked up. If you don't already have the plug, the connection should be under the front drivers side bumper.
If it going to be real cold then get the thinner diesel oil's.
I would make sure your glow plugs are in good working order. And you may need to cycle them a couple of times before starting.
When I hunt, first start up of the day I turn the key on for 2 minutes, then off, then right back on for a minute and it fires right back up. Then I let it warm up. (You will hear your EBPV when below 32*, not a problem just makes a loud hissing sound)
If all your fluids are good and designed for cold then you should be OK.
As for The Super Swampers, I would get rid of them and go with a tire designed for snow and Ice, not Mud. But then again I've never had a set, so I don't know.
