Hi Randy,
Was looking at your site and noticed your cabin cold air idea. On my six, the cold air (screened) pickup is on on the rear vertical baffle (no hose to the front). It runs to a stainless steel box on the firewall (just like the heater box) so i can shut off the air at the firewall. The air entering the cabin is approx 5 deg warmer than OAT. Down low in the summer time you notice it, but is not horrible. By the way, my six is pictured on your RV-8 site in the paint section. Love your paint scheme
