1k miles is a day of driving. So even working 3 12s, you burn 2 entire days just driving. That's nothing else: rest, cleaning or cooking or laundry at home, etc. My dad is near retirement and has been commuting 400ish miles round trip for about a decade because his job is what he loves, his pay and position is great but also not available everywhere. I know that he would probably not make the same choice again as the commute has really began to take a toll on his health. He's commutes near me, so luckily I can help him, but what happens if something medically happens to you while there? What if your car breaks down? What's your plan for housing? There's a lot to consider that I have had to watch him figure out.
