Trailers can be put to a lot of uses and just seem more versatile because you are not tethered to a front end captain's chair, steering wheel, motor, transmission and drive train. You can park an airstream just about anywhere and use it for a lake cabin, a guest cottage, a getaway space, an office, etc.
My parents went through two motorhomes at retirement before hanging it up and buying a house in Florida. I, like DavidZ, have done nothing but tent camp my whole life. This will be a new venture. Right now we are just enjoying fixing it up. We put in new roller shades this morning so next weekend we might "camp out" in our own yard now that the neighbors can't stare in at us.
