I think you're worrying a little too much about things like the wind. I-80 is used by thousands of truckers every single day, and while you certainly could see a wind storm, its not like you're dealing with 70 mph winds every day of the week. And really, I think you might be a little more likely to see those wind storms across the plains of the Dakotas and Nebraska.

But in the end, the weather is going to be what it is going to be. Wind will likely make it a little harder to handle the truck, but its really not something that I think you need to be extremely concerned about.
