When I was 18, my brother, sister, a few friends and I rented an RV to drive out to California. Since we were all barely adults, some of us being under 18 even, we got a 25 year old friend to rent it for us so none of us were really legal to even drive it. I drove it mostly and I never drove anything that large before. I only hit one person. That was outside of Chicago at a toll booth. Guy was wearing a Brian Urlacher jersey so I didn't feel too bad.
I had kicked around the idea of selling my house and living in an RV and traveling wherever there was free WIFI to remote in for work.
