So, back to the Advance Design/New Design subject. I have always understood that Advance Design was used by GM for their Chevrolet trucks (47 - 55), but I have never seen New Design used in print in reference to GMC trucks. In fact I was told that New Design was never actually used by GM, so I've always wondered where that originated.
