I'm doing great! Thanks for asking and welcome to the forums.
As for what to look for. The skins are really expensive to fix so watch out for body damage. You'll also want to test all the systems to make sure they work too.
With an ice pick. Gently probe inside the door and under the windows to make sure no water has leaked in and rotted the wood floor.
Axles are another concern so google Inland RV and there is a section there on how to tell if your axles are shot.
If you find one you are interested in just post a bunch on pictures on the forums and a whole lot of folks who know way too much will point out the pluses and minuses. (if any)
I'd rather be boon docking in the desert.
