Duramax 6.6L 4X4 actual axle weights look wrong

[lbrjet]

Before settling on a new truck or small fiver go talk to your dealer and explain the situation to them. The fleet manager is a good place to start as they tend to know about trucks. Have him/her explain exactly the differences between your 2500 and a 3500. You will find there is very little difference. Ask the cost to add the rear suspension change to your truck or even if you need it. You have plenty of rear axle capacity available. The 10K GVWR is more of a licensing/registration number than a number that represents the true capabilities of your truck. It can't hurt to talk to a more knowledgeable person than you can find on this forum.

So the dealer may be able to increase my payload limit?

[RubberNail]

Here's the simple version:

GVWR is how much the naked truck can carry in the bed and cab, with no assistance from external axles. It is limited by the combined axle capacities, brakes and the transmission/drive train. Should always be less than, or equal to, the sum of the axle ratings.

GCVWR is how much the truck and tow can safely move, assuming assistance from towed axles and brakes. Most often, this is limited by the transmission/drive train. You can look up this limitation for all the Allisons on their web site.

GAWR is how much the axle can carry and can be limited by the axle itself, the tires, or the tire rims.

Trouble comes when you have the hybrid, as in a 5th wheel, which puts a large weight in the bed in addition to the tow load. Despite numerous protests to the contrary, here the operable parameters are your GCVWR and the rear GAWR. You don't need to worry the GVWR if the rear GAWR is good because the truck doesn't have to brake the load. Folks that worry the GVWR towing 5th wheels are either confused, looking for something to worry about, or desire to gloat because their rigs are also good for the GVWR.

A side note. For the diesels, most of the 1 ton and 3/4 ton axles are the same, design being controlled by the torque, not the carried load. Difference is in the hubs, rims and tires, so there's a little room for upgrading via tire and rims. However, this may not be true of the gas engine axles.

No, a dealer can't increase a payload limit. That is set by the manufacturer, no matter what increase in springs, airbags you are set to what your door sticker is.

Which goes back to read. read..read the specific specs. before you pay any thing on a new vehicle. Specs are specs and nothing can be done to increase any of them. However you can do just one thing to drop these same numbers.

Finding an honest dealer, they will tell you what you want to hear, just to get your money.

X2 But l'm never buying another vehicle that I don't know what the exact (not advertised or told) weight specs are without an expected weight characteristics exclusion attached to it. OK I'm off my soapbox, sorry. Thanks for listening. Hopefully you cannot tell that I'm upset with myself for not knowing this before I spent $50K+ on my newer TV.

I know I'll get jumped on but I just don't see any difference between a 2500 Silverado and a 3500 Silverado. The most important thing to remember is that no one is ever going to check your weight on your truck. It's your truck and DOT is not going to stop you and check your weights. If you are worried about weights don't weigh your truck. I would bet that 90 percent of the campers that's camping have never weighed there trucks. There is no way DOT can weigh all the campers.

Sorry but I cannot do that. I can't afford the legal side if having to deal with property or personal damages if I have a problem. Keep in mind that all of my specs are easily within limits of my current TV. I just started looking at newer 5er's and wanted to know what size I could buy that will work with my existing TV instead of the other way around.

My 3500 has a GVWR of 11,500. This means, in Canada, i MUST pull into all weigh stations. They will weigh, and check my GVWR.
I can be fined for being over.

I have mentioned this here before, and received alot of arguments about it, but its true and the law. So i do it.

You mean when I go to Alaska that I will be weighed
