We had a 91 33' HR 1000 AKA Vacationer on a Chevy chassis and then a 94 Endeavor LE 36' on a Ford chassis. Never any cooling problems on either. Summer heat and humidity here on the Gulf Coast and then desert heat out west as well as mountain grades. Both good coaches but the Ford Chassis drove much better. No wander like the Chevy's bicycle tires. Ford was lots greedier though.
As far as the deer whistles, I thought they and the cow catcher bumpers were standard equipment on every vehicle where you live but those won't do you any good where they're mounted. Our good friend in Fredericksburg convinced me of that. Mine are mounted below the mirrors where they get a good air flow. I guess they work as we've never even had a close encounter with a deer even at daybreak in the Hill Country.
Hope this helps.
