It isn't a problem...that's the way they are. Once a deuce heats up
and the heat finally transfers from the engine to the transmission and
other undercarriage components, it really heats up the air under
there, and as a result, the floor gets hot.
I am considering putting down the same viscoelastic sound deadening
material such as I mentioned I will use on my M1007 in my last message
("http://www.b-quiet.com/brownbread.html") but this time for heat
insulation instead of sound, and putting rubber mats over the top. I
am alternately considering applying the material to the bottom side of
the floor panels so I will retain the steel floor and not have ugly
black rubber. Either of these applications should keep the heat out.
Also, be sure to check all the openings that lead from your engine
compartment and under the floorboards into the cab. The brake door
flap, shifter boot, and any other openings that are not sealed will
allow hot air to stream in from under the truck. This is NICE in the
winter, but very fatiguing in the summer after a 300 or 400 mile
drive. I know...I do this almost every month year around.
Good luck!
