After checking my actual tire ratings 3042 I have fixed the chart.





I would really like to have link to where I could look up my GCVW.

My truck has a gvwr of 16000 lbs and weighs 11000 lbs normally loaded. That means I
could have a trailer pin weight of up to 5000lbs. Given that most 5th wheels calculate
that the pin weight is 20% of total weight, I could tow a trailer that weighs 25000lbs. This would give me a combined weight of 36000lbs, which is over the gcvwr of 26000lbs. I would still be within the legal axle and load limits for the truck, but over the combined rating. The previous owner licensed the truck at 40000lbs so he could haul a car hauler. I currently haul a 5th wheel that weighs 14000lbs with a pin weight of 3000lbs , so I am good either way.

After hours of searching for GCWR for my truck I looked on my government web site and found this.
"“Gross Combination Weight Rating (GCWR)”; the GCWR, sometimes expressed as the maximum trailer towing capacity, may change with different engine, transmission, and differential combinations, and is normally found in the owner's manual. The GCWR is the maximum weight of the truck and trailer combined. The maximum trailer towing capacity is the maximum weight of a trailer which may be towed when your truck is empty (no payload), any load carried in the truck will reduce its maximum trailer towing capacity."

So are my towing capacity's max trailer or GCWR...?

From GMC towing guidelines. There towing capacities include everything added to the tow vehicle. It's written in big bold letters.

Could you provide the link, or documentation where it is, as you say, "Legal" to exceed the weight rating of your rear axle as long as your "Tires" rating is not exceeded. I have read in other threads where you have stated this before as well. I have searched & haven't been able to find anything on your statement.

Until I can weigh my truck again to figure out how much the family,tool box and trailer hitch weigh this is my revised chart. It is certainly going to be some value less than 14900. Some of you guys are wrong on your advice.

Bridge Formula Weights- FHWA Freight Management and Operations

This is the formula used by the DOT. Obviously I would not recommend loading our axles to 22,000 lbs (20,000 single axle plus 10% variance). I tow commercially with a CDL with the truck in my signature. I stop as required at all weigh stations and run a log. I've been inspected many times and always been found legal. I have towed a trailer as heavy as 21,000 lbs (actual not GVWR) and been weighed at the stations ( they did look at my tires).

Factory is concerned about their products longevity in the hands of idiots. If driven with common sense (don't floorboard the accelerator up hills and at starts or bury the brakes at all stops with a trailer who's brakes are defective) much more can safely be towed. GMC plans on the lowest common denominator so they do not get killed at warranty.

You are more likely to be limited by what your truck is "tagged" for, however that is not normally a problem for personal use. I am a professional and do know what I am talking about.

I am very careful to always be legal because a violation is a fine and goes against you and your company's safety record which directly affects your employability and how often the DOT inspections occur at weight stations.
