Can Aussies Stay For Longer

[Silver Nomad]

I'm not sure if this is the right place to ask this but my other half and I would like to travel the mighty US for 2-3 years. We are both in our 60's but not officially retired. We will be self funded, and not requiring jobs or social security. All we want to do is buy an RV and a truck to tow it and see the sights and spend our money in your stores. We've been told we can do this by Visa Waiver but for only 3 months at a time and then leave the whole continent, before returning to do another three months. This means leaving our stuff in storage and then flying to Europe or somewhere, (more cost) before re-entering for another 3 months. Another option is to apply for a 6 month Visa and then re-applying for another 6 months stay in the US while there. A total of 12 months. We have spent quite a bit of time travelling the country already, but no longer than three months at any one time. In fact we are heading back there for 6 weeks to become Leaf Peepers in the Tetons later this month. Coming from Australia each time means horrendous air travel costs, plus many long hours in cramped seats.

Have any Aussies done such a trip and do they have any tips on how to achieve our dreams? Could we just go into Canada for a few months and then back into the USA?
