Well, we were a little older than you guys when we started (40) but I suspect our financial position may be different as well. We also still work about 5 months of the year. During that time we live on an RV lot that we bought 11 years ago. It gives us somewhere to come back to and we always have the same doctors, dentists, vet etc etc and yes its a little bit of a security blanket. I agree with a former poster that said there is little financial advantage to full timing over paying rent etc. You have to factor in major repairs and periodic replacement of the RV. I'm also not sure how it works for Americans in regards to health care as I believe there are expenses there that we just don't have. Make sure you go in with your eyes open, be well planned with a solid back up plan and the world is your oyster. And reference that, don't limit yourself to the US. You can take the slow road south as well. Mexico, Belize, Guatemala etc. All have their merits and your life experience will be greatly enhanced. However in our experience it is no cheaper RVing in Latin American countries than the US (or Canada). I recommend you also learn spanish which is not difficult to do. There is also europe but europe can be expensive. There is also a 90 day time limit in europe before you have to leave to to a non Schengen country. For RVers that usually means Morocco in the south or a variety of northern countries. Morocco is a neat place to spend some time and a good winter destination for RVers in a non expensive environment. Lots to think about for you two. The world is your oyster. :)
Either way I wish you both good luck and interesting times. Everyone must follow their own path. There is no right way to experience life and this amazing world we live in. We are in year 11 of full timing and hopefully have a ways to go. One day at a time. We have changed so much over the years and continue to grow as we explore new places languages and cultures as full timers.
Good luck.
