We have, and would again, actually plan on it when the kid finishes college and we can afford it. We don't camp, but we enjoy the boat. We have heat and air, DVD and TV, iPod and speakers. We have a a 42, which for the two of us is plenty big. We use the generator when out, and have one PV panel, working on two more to be more self sufficient, which is our goal...leave a smaller footprint and still enjoy life.
Our favorite times are Spring and Fall until the temp dips below 32 degrees. We avoid the holiday weekends, as we enjoy our time and serenity.
Best of luck, it is not always perfect, we have had our share of surprises and mishaps and gear failures, but for us it is the best.
