I can't tell you how many times I have seen commercial dodge cummins trucks that have a DOT and the GVW in sticker letters on the side of the truck, The funny thing is its never the right # the most common # I see is GVW 30k I have even seen some as GVW 34k, for one thing no dodge cummins has ever had a GVW of more than 11,500 as for GCVW these guys are still way off, my question is where is everyone getting the #'s do they pull them from their butt??
