re: Vehicles I Do Not Understand

i agree on 2 out of 3, but the R/V can be done properly. I do agree with your assessment of what a LOT of people do with them though.

I have a nice 4X4 truck camper that can go anywhere. I've taken it deep into forests and used as home base for adventures (same with skiing, paddling, climbing, fishing, hunting, etc).

I even think the big motorcoaches can have their place. See, e.g., Justified.
