I'm am not saying this makes it right, but if I had to guess, i'd guess that over 50% of 1/2 tons pulling campers (on a summer weekend) are over their limit.

I see it all the time out here in San Diego, head to the desert for a weekend and you will see 1500's and 2500's vastly over weight with all the stuff they tow. I always worry about them not being able to stop.

Yep, no fudge factor if you are caught, well maybe less than a pound over and you are okay because scales weigh in whole pounds.

The solution is pretty easy though. Install a weight distributing hitch. Then weigh again, front axle, whole truck and both. If you are still over with the WD hitch, then redistribute has the weight you are over by moving gear to the rear of the trailer.

Here is a video showing what happens to the weight when using a WD hitch.

Again - this doesn't make it right, but when I went into a well known camper dealership to buy a new camper, I knew exactly what I wanted. What weight I was willing to pull and put on the hitch. I had it figured out well before going into the place...

When the salesman looked at my new 2013 f150 with the 5.0 v8/6 speed auto, he immediately tried selling me a camper that was way too heavy. He started telling me how my truck was rated to pull a million pounds etc... He had no real idea. I can see why people buy/pull campers that are way too big.

The value for the GVWR is calculated based on how the truck left the factory. When checking out new trucks on dealers' lots I would find 3500 trucks with a lower rating than 2500 trucks and it was a result of the wheels and tires put on the trucks. It comes down to determining what is the gating factor for your truck.

If the rear axle is rated for XXXX lbs then that is one limitation. Another is the strength of the frame of the truck. Another is the load capacity of the springs. A fourth is the wheels and the tires on the truck.

My 2500HD came from the factory with a GVWR of 11,000 lbs and a payload capacity of 2800 lbs and the limiting factors were the leaf springs and the tires. I added SuperSprings for an additional 1400 lbs of load capacity and upgrade the tires to gain 1100 more lbs of capacity at the rear axle.

The GCWR is a different matter entirely as it is based on the stress that the truck frame and its drivetrain and the engine can take. So I can increase the payload but not the total payload (with passengers) and total tow load capacity of the truck.

The gating factor? A gating factor refers to the essential task within a series of interdependent tasks which has the ability to delay the whole project.

When it comes to towing or loading a truck it's plain and simple, you cannot (legally) exceed the following:

The GVWR of the truck
The GAWR of the front axle
The GAWR of the rear axle
The GCWR of the truck and trailer (both loaded)[/list][/list][/list]

Should one cause an accident while overweight, one could be charged with gross negligence, deliberate indifference, etc.
