Life really is strange sometimes..............
5 minutes after I posted this question, I was looking up posts by another member and ran across a quiz thread that we both posted on. One I had forgotten...........
Lo and Behold, the quiz vehicle has exactly the same front end/bumper configuration as my mystery truck but the chassis was never identified.
In any case, the body on my vehicle seems to have been made by Gaubschat, which would make the vehicle German pretty much for sure. I will continue looking but if anyone knows the chassis for the photo below, that might solve my mystery.
