Looks nice for a solo traveler. The problem with all the buses or shuttle buses I see is no passenger seat. Also, I would like the back door to be able to open as a garage area or just fresh air. My bet is the lift is a body lift, but it doesn't say.
I've seen a couple of these over the years that have had a passenger seat added in for the copilot...I am sure you could source some type of RV swivel type bucket seat that would work with some minimal time and skills
