I think you are best with a TT, as long as you have a vehicle that can tow it?
There are people who live out of vans (Class B), but that is really kind of tight, and honestly, they are fairly expensive.
As a High School Teacher, you can find a nice place to camp that is near the county lines of a couple of Counties, and then put your name on their lists for Substitute Teachers, to open your opportunities to more schools, but also allowing you less driving, when you do get some work.
Living on public land is one way, but you will want to have some utilities, so you may find that a long term deal at a CG will suit you better, or at the very least, head in and spend a night or two a week, to get your batteries charged, dump the holding tanks, and get a good shower!
As a parent, I can appreciate you not wanting to put an extra burden on your folks, but also realize that if they don't mind, take advantage of it....it will allow you to build up the nest-egg, so that you can get a better RV set up....maybe $15K or so.
You can still get the $10K RV, but you may find that you are investing the extra money in upkeep.....you get what you pay for!!:)
Good luck:)
