The Dodge is cast by Dave at www.aitruckmodels.com - sleeper and non-sleeper versions.
The Big Horn stylists had planned a restyle to the COE - but Dodge killed the concept and soon got out of the Class 8 truck business. I seem to recall that the stylist/engineer who did the Big Horn had his hands on the Diamond Reo Raider too?
VERY interesting. Going by the cars on it, that is a mid/late 80's stuff on board and somebody spent some serious coin getting that Dodge up to snuff.
Dodge, Ford, Reo, White, GMC (crackerbox) all had some homely looking cabovers in the mid/late sixties. But Dodge had to take the cake with those dog dish headlight bezels. So ugly they are kind of pretty in an odd sort of way. Obviously the 1000 stylists did not play with, influence, or even talk to the Bighorn hood stylists...or perhaps they were seeking redemption.
Thanks for sharing your prototype. I would never have thought such a beast ever existed. Very cool.
