My 2004 Silverado came with the factory HD towing package. The hitch is a "V5 Talon". I'm assuming it's a class 5 from the "V5". Any idea who the manufacturer is of this hitch? It's rated for 1500/12,000 with weight distribution, which is more than the truck (2500 HD w.6L gas engine) is rated for and more than I care to hitch up to anyway! Lonnie
