I recently came across this creation in the lugnet.build.microscale newsgroup, and was immediately struck by the resemblance to the real thing. Well done! Most people would require lots of Technic parts to get something this close to reality!
Wow look! Ross has an MOCPage!! :-P Seriously cute dumper dude, the only gripe I can think of is that it'd get pretty dirty with that scheme, although making it yellow would be more authentic.
