My husband and I are planning to hit the road full time by next spring and this was a concern for us as well. I am currently studying for my certification in medical billing and coding, which you can do from home/the road if you find the right job. (some ARE office jobs, but the "from home" jobs are definitely out there) I've been a sugical assistant for 20 years, so knowing the "lingo" has definitely helped me, but ANYONE can do this if they have the patience/time to take the course. The national average pay per year for this job is $47,000+. Internet IS a must though. Good luck!!!
