(1) Review all makes and models and zero in on the configuration that you think you want.
(2) Assess your budget which will tell you whether you will be buying new or used.
(3) Find the forum for that particular option (there's a targeted forum for everything) and research the model you chose, so that you know full well what you'll be getting yourself into.
Glamping vehicles, whether towed or self-powered, are surprisingly complex machines - even the smaller ones. The number one source of buyer's remorse is people not realizing what a maintenance and repair task they are taking on when they get one. They think to themselves, "Oh, I'll just buy this, and all of my problems will go away." No - you'll buy it, and a brand new set of problems will commence. And hopefully some fun will also commence, but don't make the mistake of overlooking the ratio between the two.
An example is the new Airstream Basecamp, which is a small trailer (2,600 lbs), sort of Airstream's answer to the Casita. It looks awesome, but if you go into Air Forums and read the Basecamp threads, you'll get a real eye-full of the problems that its buyers have been having. And those problems are with a brand new unit - so imagine what can be required of a model that is older. Make sure you are willing to take on stuff like that, including the massive learning curve that goes with it, before you buy.
Edit: I didn't see the spammer advisory until after I wrote this. What the heck - there's my two cents for anyone else who may have the same question.
