Any suggestions on keeping the coach cool for passengers during the summer other than keeping the engine A/C fan on high and running the generator to use the roof unit?
A word on window tinting. If you have double pane windows putting a tint film on them will cause problems with the internal seal leaking and fogging in fairly short order.
I found this out the hard (and expensive) way with my windows in the S&B....took about 1-2 years and they were destroyed.
