Hard to say for sure to be honest, there's only like 20 beams in the image so at this point its guesswork. Personally I think it's something that nobody expects
I take it back, the T Series could actually work especially based on second image... If we get a stubby cab it'll open so many doors for cranes and stuff --- Post updated --- If it is that long it's probably some kind of crusher prop then. Or some kind of giant industrial vehicle.
While I don't agree with the garbage truck idea, I do see an opportunity to talk about cool trucks... The TC-Series is very close to the Freightliner FLA, which did come in a cab forward version. The MD is far too new to get a COE version (That would have been more appropriate for a 50's/60's MD) but refuse trucks can be found based on traditional cab medium duty trucks
