Bill and El used to fulltime on their c-dory.  They took it all over the country, camping in it on land and water. We used ours for weekends and vacations, spending up to 10 days at a time in it.  We plan on fulltiming in a land rv for a couple of years, then we want to switch to a sea rv for a couple of years. Towing a boat around is much easier than towing a tt or 5er and you can greatly increase your places to camp. As long as you can get around the lack of storage, it's a great way to see the country.
