Yeah, I see now the Grumalu is less detailed than the Proscale version, which seems to be at a similar detailing level as THS. Hub motors, like Fumotec, and Grumalu uses I would say is the most dependable solution, but less to scale. LESU offers dumper/wheel loader axles, tires and rims seperately, and also hydraulics that can fit the Proscale dumper.
