It is my understanding the NBS 2008 2500 & 3500 trucks still ride on the GMT 800 chassis. Is this true? If so, any news on a new chassis for the HD line?

Thanks

 

my uncle is a rep at the local chevy dealer here
and he as incite on alot of things and
the HD frame is planing on to be same for a good while
since no prob. with it at all
and its holding up strong

with the 6.0L wish i did get the desiel now but its still got pleny of go power
