With this level of debt the last thing you need is to buy an RV and get even deeper in debt.
There is an old saying: If you find yourself waist-deep in a hole, STOP DIGGING!
What course of study consumed most of that $70k? Whatever it was, can you make a living with it?
If not, maybe you should look into something that will actually produce an income in the near term. You mentioned Amarillo.
Amarillo has a well-respected truck driving school that is associated with Amarillo College. It is NOT a CDL-mill.
Cost for the course is around $6000 and they have dorms on campus, and assuming after 8 weeks and successful completion you might be able to hit the road full time for a few years, pay off your debts, gain life experience as well as see the country and get paid for it, and not even need a residence of your own.
With some OTR jobs you can live full time in your assigned unit and have almost zero housing expenses...or maybe the occasional night in a motel.
Today's experienced OTR company drivers can make between $40k and $120K a year...the first year you can expect to make at minimum around $30K after you have paid off your tuition, and from then on your income will only go up.
At any rate, we would like to see you stop floundering in this pool of despair and formulate a plan.
Good luck!
