I used to run my deuce in the winter here in ND and I will share what I have found!
1. block heater for anything below about 30 degrees
2. make sure your starter assist is functional and reliable
3. If your dealing with ICE in your area LOSE THE NDT tires, one patch of ice at a stop light and you will be locking your front axle in to even get moving.
4. run treated number 2 or use straight number 1 for your fuel
5. make sure your filters are all at 100%
6. get a winter front for the truck, I have one I would consider selling if you need it?
7. Drop air pressure in the tires, I ran 40 on the front axle and 25 PSI on all the rears
8. make sure your defroster is functional along with the heater.
9. Seal up your cab the best you can.
10. Have chains with you at all times just in case
11. Put some weight in the bed, preferably around 4K pounds.
My truck has the flame heater in the intake and it has always worked flawless and I have started my truck after sitting out in down to 10 degrees with no other assist, I dont like ether and dependent on where your located a block heater will go further for helping you and your engine than just about anything else on my list, I cannot recommend that addition to your truck enough!!
Everything else is pretty normal, let the truck warm up at least 15 minutes before you start moving then take it easy till your building up some real heat then your good to go!
Good luck and if you do your part the truck will do its part!
