@jshupe: you're right but we're looking at different numbers.

I assumed that rig would have a GVWR of 21K but it's only 19.5K so he's only 3500 over max tow rating.

Its just a matter of time before towing over your trucks rating will start to show up on equipment failures, tranny, rear axle or more. Those ratings are there for a reason, not just #s to look at and say ah those are just there for ***** and giggles. Everyone just needs to do what their pocketbook can afford and what they feel comfortable with.

-

*Rear axles on a dually have different hubs and deeper rotors on the end. Still an AAM 11.5 with identical gearing. AAM rates both for 10900#.
Identical engine (can be confirmed by replacement part #s)
- Identical transmission (can be confirmed by replacement part #s)
- Identical transfer case (can be confirmed by replacement part #s)
- Identical axles (can be confirmed by replacement part #s)*
- Identical brakes (can be confirmed by replacement part #s)
- Identical front suspension (can be confirmed by replacement part #s)
- Different wheels and tires**
- Different rear suspension***

**Wheels on my truck have a 4500# rating. Tires a 4950# rating. Factory had 3150#.
***My rear suspension has been completely upgraded to what is considered an upgrade for DRW trucks

What exact components are going to fail? Please tell me how my engine, transmission, and rear axle are suddenly going to fail due to a door sticker. I researched this meticulously, spending an enormous amount of time digging into parts diagrams, and have yet to find the answer. I'm well within the limits of a DRW but over the limits of a SRW. Limits that happen to be directly tied to only suspension and tires, it seems, both of which have been upgraded accordingly. The only advantage to a DRW for me at this time would be if I were getting anywhere close to the 9000# "weak link" of the wheels (4500# x2) for the RAW.

Identical engine (can be confirmed by replacement part #s) True
- Identical transmission (can be confirmed by replacement part #s) True
- Identical transfer case (can be confirmed by replacement part #s) True
- Identical axles (can be confirmed by replacement part #s)* Not True
- Identical brakes (can be confirmed by replacement part #s) Not True
- Identical front suspension (can be confirmed by replacement part #s)

Go to the body builder guide for Ford and you can find tables to support what I disagree with.

DRW gearing is 3.73. You can't get that on a SRW.

I am giving numbers for my 2012 Ford. I did a lot of research before I bought.
Other manufactures may differ, I am referring to Ford to dispute your claims.

And you can clearly see in my sig that I drive a GM. They use the same 3.73 gears for all Duramax engines - SRW or DRW. You can confirm here:

So your issue isn't an issue of SRW vs DRW, it's an issue with Ford's specs.

First, I don't have an issue, I have the correct truck for my trailer and am within ALL of my tow ratings without having to modify anything.
Second, you need to state that in your quotes as I did, what brand you are referring to, instead of making blanket statements....

First, I don't have an issue either. Yes I had to make some modifications, but you have not told me specifically how these components are going to fail when I'm within all specifications for the components currently installed on my truck. What matters are the components on your truck while doing the work, not what components were on the truck when it shipped empty to a dealer lot. Door stickers show what the truck was configured for from the factory. I acknowledge that the sticker will not change, but stickers cannot take into consideration changes made after the truck leaves the factory. I'm still waiting to hear -- from a purely technical standpoint -- what is going to fail due to a sticker; last I checked, the sticker isn't a weight bearing component. I'm not asking about legality here, as I was specifically told in this thread that my components are going to fail. I want to know why tinner12002 believes that, and how specifically tinner12002 anticipates things will fail.

Second, when I say "my" and have my rig clearly noted in my signature, I don't think it is too far of a stretch to figure out what I'm talking about.

What I was referring to was those who overload their TV either by axle rating, overloading or towing more than TV is rated to tow. I'm just saying those limitations/stickers are put on there for a reason, to give the owner an amount by which he/she can safely tow or load their vehicle and stay within the limitations of the tranny, the rear axle and chassis. Any time those limits are exceeded the owner runs the risk of premature equipment failure.
