Your right they do kind of look like tractors...and making some sort of enclosure in the tongue would work I was thinking maybe in the back so it could be inline with the doors and make some kind of worm drive with a shaft the ran the length of the dump bed...??? IDK
I'm sure there is a way to do it..... but I don't know what it is yet....so I'll simply back burner it and watch and read it will come to me eventually. I have a ton of stuff to work on so it can wait for now. Huina excavator upgrade then a Bruder 963. once those are done I'll work on the Tonka dump trucks.... then my cranes!!!!
