Thanks for your all the input.
Our interest in a boating has always been in the context of casual boating rather than full-time live-aboards. Our boating experience has been limited to weekend outings with friends who own boats. While working we always planned to buy a boat when we retired and relocate to Florida where boating could be enjoyed year round. We live in Missouri and hate the hot and humid summers here. Finally dawned on us that Florida summers would be worse than Missouri.
That's when we thought, why not look into getting an RV. That way we could travel and see the big national parks out west.
