I spent 3 years travelling overseas. I had all the tent camping gear, and could carry everything on my back, including surfing equipment, but any country I stayed in longer than 6 weeks, I found a vehicle was necessary or I would be stuck and not be able to experience the land/ sea as I wanted to, or be dependent on others, and public transportation, which is still more streamlined than in this country.<br /><br />Buying and driving a vehicle in OZ/NZ/South Africa was, hopefully still is, much cheaper, and much easier than here in the US. I Did not put much money into any vehicles there, made no improvements to them, other than retread tires and the occasional tune up which probably paid for itself in fuel.<br /><br />Caravan parks were cheap quiet and safe, and hostels charged a nominal fee to park there and to sleep in the van. Vehicle insurance was either not mandatory, or included in the vehicle registration costs. In OZ, I needed to re register my vehicle, and when they wanted an address, they had no issues listing me as a resident of a local seasonal caravan park. I was in and out of the "DMV" in 5 minutes for about 45$. <br /><br />Most of my attempts to travel in the USA as I did in other countries was met with roadblocks red tape and bad attitudes toward such a lifestyle, and I still feel like a foreigner in my own country, over a decade after having returned.<br /><br />I'd love to go out and do it again, but my funds are limited, the dollar is weak against other currencies, and in general, Americans travelers are not well liked in the rest of the world, though travelling alone and not being the typical arrogant, entitled, American traveler opens a lot of doors.
