David,
We have the same heat problem as you described being from Vermont. I have 2 small electric fans mounted behind the drivers and passenger seats. They both came from Walmart ( only could find them there) both come with clamps that I hang at the pop top clamp area spread apart. I use  an extension cord to power them up at night. I can move them aft if needed. This set up helps a lot. I also use them for white noise for my ears at night . Shuts off most of the ringing ear stuff. We are heading to north Canada in 5 weeks. Shouldn't be to hot there!
 Laters,
Dennis

I'd like the list's feeling on this.  A less expensive alternative to the window mount AC units I have seen on the list and elsewhere is a freestanding AC unit with the hose one hangs out a window.  I have found a unit that is about 14x15" LxW and 30" high, 8K BTU.  I figure I'll just strap it behind the drivers seat and on hot nights find a campground with electric and pay the price to sleep well.  On my last trip, I can remember some sweaty nights with little sleep, and that was crossing the country much further north than Rt. 66.  It was unpleasant enough with just me in the bus (wife flew out to meet me in CA (less rime off than me), and after Yellowstone, flew home from Denver) so I can imagine with 2 of us for the whole trip, that will double the discomfort.  So does this option sound OK, or am I on the wrong track?  If on the wrong track, why?
