Sorry didn't mean to confuse anyone. Tire capacity is 3195 each rear tire for a total of 6,390 lbs. The rear axle weight (GAWR)limit is 6,010 lbs. is lower than that so I'm using 6,000 lbs. for my rear axle limit. I have nothing to gain by increasing the tire capacity.

Rear axle weights:

Rear Truck weight (empty): 2,570 (as per door sticker, not weighed)
Hitch weight: 1,930 (as per brochure, not weighed)
Cargo: 400

TOTAL 4,900 + passenger weight of aprox. 300

I think I will be below my GAWR for the rear axle. Unless I'm misunderstanding something.

Since your are asking the question I am sure you are a safety conscious person and if you know this truck is overloaded you will never be quite comfortable with it especially if you pull in the mountains or other tough places.

I had the same situation being about 800 lbs over on the GVW. Although I was not over on either axle and the truck pulled and stopped just fine I just wasn't comfortable. I finally traded for a dually afer 4 years. This changed the camping experience for me but I must admit I am pretty anal when it comes to that type of thing.

Happy Camping

It's your tires that are limiting, not the springs. You already said you have 3195 lb tires. How does adding 760 lbs of extra spring increase your tire's weight load capacity?

That's why a 2500 and 3500 have the same payload. It not the truck that limiting the payload, it's the tires!

Why do you think a 2500 and 3500 SRW have the same payload?

I can assure you they are different - the 3500 SRW has a higher GVWR and about the same curb weight, so that makes for more payload...

the trucks payload isn't genric. In other words one size don't fit all. Each truck has its own payload that is determined by weighing the trucks rear axles. Rear axle will carry the 5er pin weight. Case in point is a truck operator that has added a 250-300 front bumper with a winch/maybe a heavy suspension lift/huge tires and wheels that may be half again the weight of stock tires and wheels/4x4 option/other heavy options/more passengers/large aftermarket bed mounted fuel tank/etc. The truck now weighs much more than stock. MFG payload number just went out the door.

The '06 2500 has a 6000 RAWR. The '06 3500 SRW has a 6400 RAWR (3195 x two tires will be close enough to 6400 lbs).

The biggest concern on loading a truck is going over the trucks axle and tire cap numbers. Pulling and stopping a 5er at max axle/tire cap loads is something many folks aren't comfortable with. Many of us have no issues with hauling max axle/tire caps.

The 5er in question pin weight is a estimate only which generally a 20 percent of gvwr can be used for a estimated pin weight

I have the same truck (see sig) and the rear unladin weight is 2780 lbs with no folks and a full tank. That leaves my particular truck with a 3220 payload. Figuring the sliding hitch weight/all the folks and other stuff I'm left with approx 2600 lbs for a max pin weight before going over axle/tire capacities.

If you decide to get the 5er I would get it weighed. Pay particular attention to the trucks rear axle as it will carry the 5er's pin weight. If its over your present tires capacities its time to upgrade tires.

There's a difference between "law overloaded", and "law of physics overloaded". Just because you're over GCWR doesn't mean the truck can't handle it.

IMO tire and axle load ratings should be followed, as they have minimal effect by marketing. Even then, all load ratings are not created equal. Two tires with equal loading rating, one could have a much stiff sidewall and therefore handle the load, or even over-load, much better than the other.

If you guys are concerned about weight, look at these "hot shoters" and see how much they carry. They're all "legal" in that they're DOT registered for their 35,000 lbs GCW.

You need to step on up to a 3500 Dually for that trailer. The 2500 and the 3500 Dually ARE NOT the same trucks except for the springs.

Another point of clarification...I was referring to the difference between the SRW 2500 and 3500, not the dually. I have parking restrictions at home and work that prevent the dually option for me.

Thanks for the feedback. My last round of calculations left me with a Gross Vehicle Weight of 9,350. Truck's GVWR rating is 9,000.

...If I keep crunching these numbers enough I might be able to pull this baby with a half ton.

Yeah, the dually has the extra tire, badging, clearance lights and fenders also. Brakes, Axles, drivetrain, frame are indeed all the same between the CTD series of truck. I do know this for fact as I have done the part research. This applies to 3rd gen Ram's with CTD only, I do not know about the others. It makes sense too, it keeps the R&D down, the tooling down and simplifies things. I would tow anything with my rig that a SRW 3500 was fit for. That said, if I was the OP, I would be using a dually for the camper he is referring to. Anything close to 3k on the pin is dually material in my eyes, but hey, to each his own.

After having driving a 2500 srw for four years and finally moving up to the 3500 dually,I can now see what everyone is talking about when they say overloaded. Its not the fact that the 2500(probally a diesil) won't pull as good as a 3500 and up dually, it's just pull the same load with a dually and you have the answer. There is a differance between pulling, handling or stopping a load. This is where we all get caught in "Tit for tat" arguement, but just remember that most of us(myself included)have went through the same delema as most that have the 2500 of all brands. I realize my words will fall on deaf ears if you have not been able to make a towing comparison with a 3500 drw truck compared to the 2500srw. Just my humble opinion.
