Hi Katrina, the biggest thing is the money. If you have a lot then you can get a lot of nice rv's. I think if you have time and some skills then built your own campervan. We have a lot of different types of campervans in Germany but they are very expensive and the are not really useful for me. That's why I built my own. It takes a lot of time and it's not so perfect like a new one but its self made. For my next I will take a 4x4 truck like an old firetruck from the 1970 or 1980 but for now I bought a Mercedes Sprinter. I will be finish with my campervan in 2 months and then I will start traveling.
