I have a 5th wheel. For our purposes, it is the best choice for me IMO short of a motorhome that costs 3-4+ times as much, but my choice would be different if my uses were different. If I was touring the country, etc., it would be a pain setting up, packing back up, etc., every couple of days.
Ours is a beast, but it's for the family plus son's friends. We don't go place to place much, usually just to one place per trip. It has most the comforts of home (and more than a hotel!), but we can be in places out of the city.
