Also check to see what AC units were installed. Our 40' Allure with two slides, had two 15K BTU units installed, and we can cool the place down quick with both on. Then maintain temps with only the rear unit on and closing off some of the vents in the bathroom/bedroom area (I always leave one open in the bedroom) pushes more of the rear AC's air thru the shared ducting. This keeps the loud AC fan noise in ther rear of the coach, and yet most of the time this keep us comfortable in the front. We've only had one time when temps were about 105, that we had to turn the front AC on for 10-15 mins out of every 60-90 min period, to help bring down the temps.
We do have and use the ourside windshield screen shades, for both privacy too, but mostly this is the largest area of heat gain/loss from the coach. Can still see outside too.
You might find your rig your looking at with the two AC's, had the optional 15K BTU units.
Best of luck,
