I still haven't been able to find an explanation for a side mount versus a rood mount unit. Cost to reinforce roof?
I think the side mount AC is the right tool for the right job (5-8K BTU) for the 145, 154.... the space is small, the ceiling is low (6'-1") and there is not much roof space available....we would have lost our living space roof vent on our model (which we enjoy).
The wall mount design seems marginal for the 185....but again with a 6'-1" ceiling height, a roof mounted unit AC would probably be annoying blowing in your scalp and eyes everywhere you stand.
The 16XRB is a different animal....higher ceiling height, compartmentalized design (rear bunk space partially obstructed by the living space). Also...the roof mount AC is 13.5K whereas the wall mount is 8K....and (IMHO) you are going wish you had the extra BTUs considering the inefficiencies of (2) expandable bunk ends (if you camp in a warmer climates).
