Jeff, I replaced the roof on my house, garage, a small barn and shed this
summer and used a product that sounds like Ice Guard.  The stuff I used is
Sure Grip Ice & Water Guard [or some name similar to that - I can give you
the exact name later if you want].  It comes in a roll 3 feet wide x 65 feet
long for about $90 locally.  It is a black, flexible material with a plastic
sheet that you peel off on the back to expose the adhesive.  The front has a
rough texture that looks like a great non-slip surface; HOWEVER, it wouldn't
work for walking on because if the sun is shining on it and you step on it,
the surface gets torn up worse than working on hot shingles in the sun.
Although it would stick well to the inside of your truck, I can't imagine
using it because it has a significant bituminous smell that I always notice
when I walk into the building that I have it stored in.  I don't know how
long the odor would persist, but I think that the sun heating up your
enclosed truck would make it even worse.  Other brands may have a different
composition.  This stuff shouldn't be too exotic if you live in a region
that gets snow so you might be able to get a scrap from a contractor or
roofer or see it at a lumber yard.  
     I also used an EPDM rubber membrane on a flat area on the house roof.
This was a huge sheet of rubber that looked similar to inner tube rubber
[0.060" thick] that was glued down with a contact cement.  The cement had
solvent vapors but they subside as you let it dry before installing the
rubber.  It could be tricky to work with inside a truck cab, but some big
magnets would help hold position as you worked with half of the sheet at a time.
     Hope this helps, Mike
