Drove day before yesterday with 30 mph tail winds and had a relaxing drive towing our Wrangler at 65 mph and 9.9 mpg. Drove yesterday with 20 to 25 headwinds and side winds, very stressful and tiring. Got 6.2 mpg at 65mph. As said previously is it worth it and do you feel safe. One trip a few years ago the winds were so bad I finally stopped and took a nap as I was exhausted from fighting the steering wheel, fuel mileage down to 4.2 mph. I had a destination with a meeting I had to attend, after the nap winds subsided and one our way after dark. It's up to you what your comfortable with and being safe. Personally if I don't have to be some place I take the day off, this is supposed fun not work.
