Why does the RAM website contradict itself on Tow ratings?

Ok just an irritation here I'm trying to figure out what the exact maximum towing capability of my 3500 Chassis cab with a flatbed on it is. I go to the Ram website and look up chassis cab and they say that my truck in a dually form crew cab 4x4 with the Aisin and 3.73 gears can only pull 21,950. The only way to supposedly pull the 30k they claim is with a 5500 This doesn't make any sense. What am I missing here?

30k lbs with the 3500 dually properly equipped
28k lbs I think for the 5500

The Cab & Chassis trucks have a lower hp & torque rating (generally for fuel economy reasons as well as fleet reasons) than their pickup counterparts.

So I basically bought a truck I thought could pull around 29k that realistically can only pull 21k? is it just the power difference that decreases the tow rating or is there a structural difference as well?

The pickups have the AS69RC AISIN vs the AS68RC in the C&C; the pickups have 385 hp & 850 lb ft torque vs 325/750; the pickups have an 11.8" (300 mm) rear axle vs the C&C 11.5" rear axle....perhaps others can chime in, but there's probably more.

***EDIT*** Maybe the C&C trucks now have the same AS69RC as in the 3500 pickups???

Hmmm that's an interesting idea. I'll have to check my build sheet when I get home. I think it has the AS69 though. But having the same rear axle as my 06SRW is a little depressing. I was hoping for something heavier duty there as well. I'm thinking I should've done more research before buying

Yea -- But if I read the figures right, your 3500 C&C PAYLOAD capacity crushes the regular Heavy Duty.

As for the power numbers -- I think they detune the C&C trucks SLIGHTLY for DURABILITY mainly. I've seen it many times. For example, the new 6.4L gas engine from the SRT is being made more robust and yet their detuning it for the truck for durability.

I'm a firm believer in never looking back. If this truck was good for your purposes when you bought it, it doesn't matter what a 4.10 AISIN 3500 Heavy Duty can do.

Just my $.02.

I look at it like this. We have four Cab Chassis (along with other trucks with a less GVWR). Everyone drives these Cab Chassis trucks. Additionally, we have a couple guys with CDL's that pull goosenecks with these trucks.

I would prefer a slightly de-tuned truck that multiple drivers operate as compared to other trucks that one guy drives. A buddy of mine years ago worked at a place that had a box truck with a 460 gasser. Multiple drivers blew that thing up multiple times. Then they put a straight-six in it and it lasted.

I like your thinking.I was getting so hung up on the numbers and not paying attention to the fact that it still has more than enough to pull my 5'er

My father always told me after I bought something -- stop shopping. You're out of the market. You can only be disappointed because it's the American Way that something newer and shinier is coming right around the corner.

The C&C trucks are commercial grade. They know businesses and so forth are going to use them to their limits and beyond. So whatever ratings they have, I'd be more comfortable meeting or exceeding them in a C&C than a Heavy Duty.

According to Allpar (They're sometimes wrong), the C&C has the new AS69RC like the 2013's. See 1/2 way down the page here: http://www.allpar.com/trucks/ram/2013-chassis-cabs.html

"The new Aisin AS69RC six-speed automatic transmission has more robust components and a new control system that improves shift quality and drivability. It enables a left-side power take-off (PTO) option and allows for a split shaft PTO configuration. It has a higher output (45 horsepower/250 lb-ft torque) case-mounted, larger floor patch plate, and relocated exhaust."

Not even close to being the same engine. One is built for sheer racing power and one is built for pulling.
