The Hunter 216 should be easy to trailer, rig and launch. The fractional rig will make it easy to sail. It has a ballasted centerboard, so it will be more stable than a small, unballasted dinghy. It has a small cuddy cabin and vberth, and will accomodate a portable head. You could probably spend a few nights camping on the boat in fair weather, but you wouldn't want to be cooped up inside the boat on a steamy, rainy day. You should be able to tow it easily with a midsized suv.
It's nice if you learn how to sail on a small, unballasted dinghy, but I learned on a 25' ballasted cruiser, as did many of my sailing friends. If you have the desire, you'll learn on any kind of boat.
