The origininator was from Montreal ... A/C == open the window

I mean how often does Montreal get 100* days?
Even in the PNW, a hot day isn't bad in shade or with top/windows down.
Course a FRIGGIN desert is a different story! So do you really wheel in a desrt with top on and windows up?
(I can see A/C being a good thing ... I just see that in a used rig, it's probably another thing to fix)
