Think it does have side markers,as I recall. They just don't show up in the pictures. But,the knobs on the dash and seat belts are the 68-72 type
Pretty funny it has GMC on the hood,huh? Hey!...See?...That's '68 too!!! Maybe they weren't around long enough for the toy designers to notice the proper do and don'ts.
Ertl made Matchbox sized GMC die cast Fendersides that say Chevrolet on the tailgate. I guess that makes it even. This thing even has the right wheel covers. I'll prolly never see another. I like camper stuff,too. (Glad I didn't have to pay $50 though)
