I live in Vermont and have a few winters under my belt. The last few have been with a Subaru Outback equipped with snow tires. I have a 20(x2) mile highway commute five days a week. I am going to put snow tires on my 2011 TRD Sport Double Cab. I'm skilled at driving in snow, but have never driven in snow with a truck. Here are my questions:
1. When driving at highway speeds, should I leave it in 4WD?
2. How much does driving in 4WD affect gas mileage?
3. Should I weight the back? (I have a hard tonneau cover.)
4. Any tire suggestions/warnings?
Thanks for any advice.
