I'm nowhere near retirement age, but why not do both? Do the RV thing first, you don't have to buy a tour bus to enjoy a few years of the RV lifestyle. Then, when you get tired of it, or your health makes it more difficult to travel, buy the condo. Or, buy a very small condo (smaller than you would live in full time, like a 1 bedroom or studio) as a landing pad, but spend most of your time RVing. That way if you ever want a break, you have a place to do it, but you aren't bogged down by a more expensive/larger place.
