I'm spending the summer on a truck with my mom (long haul driver) and my brother. What's surprised me is how much of your life revolves around the job. Truck driving is really more of a lifestyle. In our case, the electronic log books have a lot of say over when we can and can't drive, meaning that we won't always be allowed to drive when we feel up to it, and you we have to drive despite being incredibly exhausted. So I'd suggest reading more about the difficulties of working with electronic logs.
You might also feel limited to rest areas and truck stops. It's hard to find truck parking other places. Even shopping for groceries at Wal-Mart can be extremely difficult.
You can make a good amount of money from truck driving, however, because you don't have to pay rent (if you don't already have a family to support, that is). You might be able to save a lot of money while you work. Then, if you get tired of truck driving, you'll have a nice amount to invest into settling down somewhere. Plus, you'll have the advantage of seeing the whole country and deciding where you'd most like to live.
