The following was semi-scientifically tested by me in the nice hot
Metro DC area summer. I would quote you the exact numbers but I can't
seem to find the document where I wrote up my results so you'll have
to put up with my general memory of the temperatures... If you don't
want to wade through the whole thing skip to "Conclusions" at the
bottom.
The vehicle was a white 1999 Honda with slightly tinted windows.
The camera bag was a Tamrac System 6 (well padded/black cordura
exterior)
The blanket was a heavy "Chief Joseph" wool camping blanket.
The Cooler was a cheap soft sided dollar store model large enough to
hold 12 cans of soda (two sets of six, stacked on top of each other).
The exterior of the cooler was light blue and yellow.
The thermometer was an inexpensive Radio-Shack indoor/outdoor model
that records the high/low temperatures.
---------------------------------------------------------------------------------------------
Thermometer anywhere in the main cabin of the vehicle maxed out at
138.8 degrees (all reading in Fahrenheit). I would guess the total
temp was possibly as high as 150 degrees.
Main cabin with thermometer inside Tamrac bag was significantly cooler
IF THE BAG WAS IN SHADE. (somewhere around 95-100 degrees).
Main cabin with thermometer inside soft-sided cooler (no ice or
blueice, didn't want condensation issues). Significantly cooler in
both shade and sun (around 95 degrees max)
Main cabin with thermometer in cooler and in Tamrac bag while under
Chief Joseph blanket were both around 90 degrees.
Trunk
Trunk stayed significantly cooler at about 92-98 degrees.
Trunk with thermometer inside Tamrac bag was significantly cooler,
somewhere in the 88-90's.
Trunk with thermometer inside soft-sided cooler (no ice or blueice,
didn't want condensation issues). Significantly cooler (around 80-85
degrees max)
Trunk with thermometer in cooler and in Tamrac bag while under Chief
Joseph blanket were both around 80-85 degrees.
CONCLUSION(s)-
1) The trunk was always better than the main cabin.
2) The cheap soft-sided cooler helped a lot.
3) The thick wool blanket helped a lot if the equipment was in the
main cabin, especially if it was in the sun, but made little
difference in the trunk.
Since trying this experiment I usually keep my gear in it's carry bag
(the Tamrac bag) which then rests inside a big soft-sided cooler in
the trunk. I do NOT use ice or blueice as I would worry too much
about moisture issues.
Of course YMMV.
