Towing capacity?

I know my 2005 duramax is rated at 12000 GVWR but when I was in the heavy equipment business, building roads,etc. The pickups were usually 3/4 ton Fords and they were hauling backhoes and small rollers and assorted other pieces of heavy machinery using big bubba trailers all over the mountainous western US. I bought the duramax to out do those Fords and when I was in the biz I only towed a small 17' 3,000 lb travel trailer. Now I want to upgrade to a 28' 5th wheel that weighs around 11000 lbs. That only leaves 1000 lbs before I reach the GVWR according to the sticker on the Driver's door and in the owners manual. Somewhere, I can't remember, I heard that I could actually tow up to 15,000 lbs. One of the mechanics in the biz who had a 36' 5th wheel, towing it with a '88 3/4 ton Ford gas model was going to a 40' 5th wheel. He told me it was the hitch weight that mattered not the GVWR. My question is how much weight can I tow with my 2005 chevy silverado duramax diesel

Gross Vehicle Weight Rating on a DRW 3500 is 11,400k lbs. The empty 'Wet' weight (Crew Cab) is approximately 7.3k lbs, leaving you with a rated capacity of 4.1k lbs for passengers, cargo and trailer pin weight.

With a fiver weighing 11k lbs, figure 15% or 1,650 lbs of pin weight. That leaves you with 2,450 lbs for passengers and additional cargo.

The rated towing capacity for a GN/Fiver on a DRW 3500 is around 15k lbs.

You should address the LLY turbo mouthpiece problem to ensure a problem free towing experience and you'll be fine.

My 2007 LBZ is commercially licensed for 36k GVW but the most I've pulled is just over 34k GVW. I pull a 45' lowboy flatbed all over the country with my rig and the only problem I have is an occasional DTC P0087 which can be fixed with a shim kit according to IdahoRob.

I kinda don't even look at the trucks GVWR or the GCWR I just pull if the truck feels it can't or doesn't want to pull the load I will switch trucks.

Oregon,

How do you license a truck to tow over the manufactures ratings? While I agree that it is most like capable I would like to know the process of such licensing. Does it simply require the proper DOT numbers and CDL drivers license or is there more to this process?

Some states base registration fees on the declared maximum weight going over their roads, and not the mfrs stated gvwr. Get caught over what you declared and it's $$$$$.

It's a fee/tax/fine for a money grab, and not based on much of a safety factor, IMO.

Not much difference from other states that would charge for the truck based on 11,400lbs and then license and charge a GN with twin 12k axles...36k GCWR.
