You gotta read this!! Mega-dually

[RustyJC]

Actually, I didn't decide that 7500 lbs is the axle weight limit. 7500 lbs @ 55 PSIG is the rear axle GAWR shown on my driver's door sticker.

Mr. TEE

Let me start off by apologizing to you if you took any of the comments about the MCDually personally. You are totally right that every truck ever built has a satisfied owner out there somewhere. When I started the thread I had never seen a MCDually in person and had never read a thread here that someone actually owned one.



First off, I drove a 2004. 5 2500 all dude'ed up and thought it handled my 2006 36' Cedar Creek great. I also ran it with a pin load of 3k and the truck handled it great... EXCEPT for the tires were at there limit. That is one reason why I purchased a 2006 dually. I still don't like a dually. I personally like a short box. Beside all of this, I did look at the MCDually very close and was impressed with the way it was built and still don't like the fender flairs... I have made my point many times on TDR that althought trucks are designed by the factory to carry a certain load and you have those that totally ignore capacities and those that try to stick & adhere to factory specs, I would not call them Nazis. :-{} It just does not figure why Dodge would build a truck with exactly every component of my 2006 QCdually and give it such an under rating on the GVW. If "legal" is such a word and can be applied to hauling a load then why build a truck that can only place 1500 pounds in the bed?



Either way, you have a great truck and I hope you get many years of enjoyment out of it.

Hey Cumminz

No appology necessary, all in good fun, I enjoy a good banter, probably a little too often



And you do have some very valid points as to why would DC de-rate this truck when it has all the goods to be just like its long bed QC big brother



You have a PM,









Or at least you will have once I get out of the hot tub, wifey calling Gotta go





Edited after hot tub trip for spelling and gramer errors - sorry guys, I just couldn't help meself, I needed to hurry and get in that hot tub

After many years of being a family that OTR's for a living I can tell you this much. The manufacturers GVWR don't mean squat to the DOT (within reason). All they care about is the rating on your tires!!!! And in a OTR trucks case the distance between axles etc. The tax people care about what its REGISTERED for, not what that little sticker says in the door jamb.....

Ding Ding Ding we have a winner.



I don't know about other states but in Kalifoneea this is true.

The GVWR will be used to determine your reg fees on a truck of 10000 GVRW or less, or a factory pick up box truck of 11500 GVRW or less. (unless you come in from out of state you need to go get a weight slip to register)

In addition you are exempt from motor carrier permit issues(like D. O. T. # M. C. # Etc. ) with the above GVRW's. There is no law (can't get an overweight ticket) for exceeding your GVWR or your CGVWR. You will get in trouble for exceeding the limit on your tires.

This is more common than you think when a guy has to have the coolest 35"+ mud& goo supercool tires but doesn't realize most of those are "D" range at best. He then hooks up the 14000# toy hauler with a gillion # tounge weight and the load bars put on wrong. After a scary trip out and back he cusses the tire manufacture for a junk off road tire that wore out so fast.

I think most of us that work our Cummins' anywhere close to its limit have gone over the GVWR/CGVWR. But if you stick with the right tire(s), and proper load balance you will have smooth sailing.

Boy, we diesel guys get smarter everyday ... . hehe



The tire issue is why I went to a F rated 12 ply tire on 19. 5" rims. I tow a 35' 5th and the stability of these over even the stock E tires is wonderfull. CUMMINZ, you should have done that than get a dually...

A 3rd gen 2500 and 3rd gen 3500 have the same brakes (close enough) so whatever the rear GAWR on a 3rd gen 3500 dually is, that is what your axle is rated for in terms of brakes.



Check out readers rigs Gerg Boardman's dually conversion, the dually's rear axel is longer, and the brakes are larger. The photo's clearly show it.
