That sounds like fun! Mr. Ex and I have talked about getting one of those outrageously expensive RV's and travelling around the country when we retire, for as long as our health will permit.
We'll keep our house (that we plan to buy very soon! yay) after it's paid off, and make necessary accomodations, rather than sell. That way, we can have our cake, and eat it too. :)
Yeah, you don't need a too expensive rv, but we sold our house after reading several books on Full Timing. the idea of renting it our did not appeal, and we could not even drive to our house with an rv, (streets to small and no parking). Lots of ppl do keep their homes, or even buy in a community that supports rv'ing, such as the Escapees rv club sponsors. Look into books and check out the escapees club for ideas to help in your planning. We started going to RV shows 5 years before we actually retired.
