I don't know about the rest of you, but my diff gets pretty darned hot when I tow. Always has. You're not going to lay your hand on it very long after a trip on a summer day. To me, that's over 200 degrees.
140 degrees is hot enough where you are not going to want to lay your hand on it, and that's still pretty darned cool by lubrication standards.
If you can hold your hand on something even approaching 200 degrees, you must be from another planet.
Regardless, there is no way for the differential to transmit noticeable heat to the floor of the pickup bed, UNLESS the truck is a slammed low rider, OR the differential is on fire.
