Check around. You should find 1 made to fit 1 of your roof vent
openings. I've seen them mounted on the tops of RVs in AZ.
Here is 1 such model:

Might be possible but the Evap cooler would be useless during most of
the summer months when the dew point is too high. Great for the rest of
the year.
Check around you. I think the humidity might be too high in Riverside. Of
course, if you want to move to, say, Barstow ....................

Not sure why you even want to cool it when it is parked and empty...
I had mine parked (and hooked up) behind my garage, and just had a temp
control fan with the maxair vent (so rain wouldn't fall in).. If I wanted to
use it, then (and only then) I would kick on the ac. Could use the turbo max
when I was out and about too.
