 Windows, I have wheels, and it's a mobile office. It's kind of nice where I don't have to do the same thing or see the same four walls every day. Another perk? For the last year and a half, he's been driving electric trucks, where the loudest thing besides the radio is the turn signal. You don't hear the engine noise, and you're not hearing the shifting and the RPMs coming up and dropping every time you go through a shift. So after driving this many years, it's kind of nice not to go home with a noise headache from road noise and or from the truck itself.
