"Reflective
is great if OUTSIDE of the Van. We have made prototypes of inside and
outside thermals and found that inside ones are a waist of time. will
stop the sun from fading the interior but nothing for heat. If on the
outside of the Van it will stop the thermal transfer of heat and or
cold from coming to the inside of the vehicle through the glass."

.... which is why I LUV your front (windshield/driver/psgr windows)
sun/bug screen. Great for keeping the bugs out, air circulation in,
and leaving the windshield sun shade down (not rolled up) is very
effective for blocking thermal transfer there, but even with that
rolled up, it's still real effective.

Nice seeing you guys near Glacier and glad to see you got home
OK.
