We decided when we are empty nest that we will buy a small casita, simple to tow, and tour the entire country for months at a time. We are already cozy in our small RV. The class A Bounder we have more room in of course, but it's not majorly important to us. Ease and comfort of travel (and simplicity in travel) can be nice too. A's & C's are nice for us with children. We can even bring a toad. But I think we are going to go with a tiny TT later, or perhaps even a cabover. This way we can tour the country, both city & countryside.
