Looking for a Motorhome for permanent residence

Here's my adult advice to you. Don't do this. Go find a real job and start working on saving for retirement.

Now here's my real advice; Go for it. I sort of went on a travel expedition after I got out of high school, but it was with the Air Force. I wish now I had done something like you're talking about. Even for a year or two. It will be a good education for you.
