SRW vs DRW

Is there a general rule regarding how much weight is okay for SRW and how much is too much? We are thinking of a larger 5er and not sure how much larger will require a new truck too.

"Tow ratings and vehicle ratings are matters of engineering."

NOT always the case. The 14k GVWR on newer DRW trucks is a false limit to keep the trucks in the class 3 instead of going into Commercial Division where licensing and insurance costs would dramatically reduce 350/3500 and yes even the 450 sales.

Why would they have my SAE RAWR at 9,750# and without adding a single # to my factory front axle weight make me over my GVWR by 1,000#?

Also if it's so illegal why do licensing departments sell tonnage in 2k increments.

Take all this YOUR GONNA GET SUED with a grain of salt.

It doesn't matter what your state says. If you're over your GVWR, you're overloaded.
If you need a law enforcement officer to ticket you in order to ensure you're loading your truck safely, I don't really know what to say.

Please! Let's stick with what is actually the law and not what someone think the law says or wishes the law said just to support their unsupported argument. People who spout off that stuff have never read a law or most likely even know where to look for it even if they could understand what they read.
No LEO is going to give him a ticket for being over the manufacturer's GVWR. There's a very simple reason why. The manufacturer's GVWR is a rating by the manufacturer. It's not a legal weight limit. Manufacturers do not make the law. It is a non-enforceable rating used only by the manufacturer for their ratings. It's not a legal document and has no bearing on legal weights.
I didn't get my knowledge from listening to some fat guy in a flannel shirt sitting around a campfire. I taught truck laws and weight laws for a lot of years. I was recognized by the courts and FMCS as an expert in truck laws and weights. If a person is going to use a legal comment to support their personal opinion then post the statute. At least it might show the person knows what they're talking about.


I can't get into an argument with you about the law because I am a lawyer and I wouldn't want anyone to interpret any of this as legal advice. Google "accidental client" if you need an explanation as to why. I can tell you that the sources of law in the United States are many and varied, what may apply to a given situation is generally pretty difficult for a layperson to apply. I can also tell by your response that you're not a lawyer, because the United States has 50 separate state's laws interacting with a myriad of federal statutes and administrative regulations in such a way that broad pronouncements like you made in your post are simply not possible. Were you to consult a lawyer in the relevant state, you could probably get an opinion on what the rule of law is for that state. I can say that the idea that you cannot be ticketed for loading beyond GVWR anywhere is false, as I am aware of places where that is not true. Regardless, you could still find yourself in serious hot water--with a court or your insurance company or worse--if you operate a vehicle that is unsafe. In those circumstances, it may not matter if your combination was legally licensed or not.

Tow ratings/vehicle ratings are not a matter that requires a legal discussion in any event. The law, in some instances, sets the minimal moral standard. Many of you posting here seem to be of the perspective that if something isn't illegal, it must be a good thing to do or therefore safe. A high school civics lesson is in order for those people--the government should not be setting your moral standard. I could go into the many examples of conduct that may be legal, but most would find questionable at the very least.

Tow ratings and vehicle ratings are matters of engineering. I leave those judgments to engineers and the companies who are willing to stand behind their products when used as intended. Just like I don't take twice the daily dose of Tylenol and hope my liver survives, I don't overload my truck by 20% and then pray it holds up in bad weather or an unforeseeable crash. I'm also not willing to risk finding myself in court explaining how I knew my truck was rated for x and I deliberately loaded it to 1.2x and took off down the roadway, endangering the public.

A person who is aware of a substantial and unjustifiable risk and takes it anyway could be charged with a crime if that risk caused injury or death to another person. I'm not talking about a traffic ticket or a fine. I'm talking about if you lose control of your vehicle combination and it kills someone, you could find yourself in prison.

I also couldn't say for sure, but I have serious doubt that an insurance company's policy would cover those circumstances. Insurance companies aren't exactly looking for ways not to pay, but they also cannot anticipate all of the ways people will use their vehicles beyond their manufactured limits.

The interesting thing about this discussion is that nobody would stand under a crane lifting 12,000 lbs on a rope rated for 10,000. Everyone knows there's an engineering factor in there, but none of you would put your life on the line to find out how much. The day is coming when RVers are going to be subjected to the same kind of scrutiny that commercial drivers are, because RVs are chronically overloaded and it's a miracle that they aren't involved in more incidents. All it's going to take is one high profile incident to end that forever, though, and I'm amazed every day that it hasn't happened already. We require special licenses for motorcycles but very rarely so for RVs, and yet many of them are very severely overloaded, perhaps even unknowingly.

If you need the law to tell you that your behavior is unsafe, I just hope we never compete for the same stretch of roadway.

According to these weights and based on a 20% pin weight my truck can tow:

Based of GVWR:
Pin weight can be 3180 lbs
So Gross trailer could be
15900 lbs based on a 20% pin.

Based off GRAWR:

Did you have the hitch, full tank and occupants in the calculation? I'm assuming so.

Yes the fuel tank was full and B&W hitch was installed when the truck was weighed. Weight was with driver .... no passengers.

Agreed, BUT...... Bottom line is what does your LOADED rear axle weigh??? Big AZZ tool box or the 80+ Gallon fuel tank or all the stuff loaded in the back seat and bed.

This guy thought he was jUST FINE. Basically had 6,200# or so capacity on those 17's. Asked if he had ever weighed his rig, looked at me with the why would I do that look. I politely said you may want to do that.

NOT really, I can tow 30k or so but in a two axle 5er with 25% pin no way and stay at or under 9,750# RAWR! I look more at what the RAWR is.


Clarification: When I said "pull" I meant as in "pull from the internet"

"Ratings" is plural implying all the truck ratings are within spec.


OK, understood.

I still stand by what I said. Just because they say you can pull it does NOT mean you can carry it! Different type trailer will give different load.

RAM and I think FORD rates the 3500/350 SRW higher than 15K, I tow a 16K 5th will just fine with mine. If I was to tow the max 17,050 trailer, then I would have to remove a lot of stuff I carried in bed boxes to stay below 7K RGAWR.


Yes Chris, many are towing over 15K with their SRW trucks, and I think Ford or Ram can handle 16K FWs in many cases. One FW with actual gross wt of say 15,500-16K, could have a much higher pin wt, depending on floor plan, which may limit what can be added to the truck bed, basement, or maybe even walk-in front closet.

IIRC, you are running pretty close on your rear axle with your set up. You have some nice boxes added, and others may want to add extended fuel tanks as well. So when I suggested best to consider DRW, when GW of trailer is more than 15K, it would remove most worries of additional bed wt, or higher than normal pin wt.

Thanks everyone. There is a wealth of information here. I checked the weight tag on my truck and found the following information: GVWR 9900, FRONT GAWR 5200, REAR GAWR 6830.

That increased the towing capacity of the truck, but I don't remember how the truck shop calculated those numbers. Can anyone determine the maximum weight 5er this truck can tow?


It's not what you can TOW, it's what you can CARRY, i.e. PAYLOAD, that's the critical number. Sure, you can tow more, but you can't CARRY any more than you could when that truck rolled off the line. First thing you need to do is to load up your truck as if you were going camping. You, passenger(s), hitch, full fuel and "stuff", then hit the scales to see what your truck weighs. Subtract that from the 9900 lb GVW from your placard. THAT is the PAYLOAD capacity that you have left to CARRY the pin of a FW (or GN). If you =really= want good #'s, then take the FW with you to the scales and weigh =all= axles, steer, driver and trailer, both with and without the FW hitched up. Do it ready to camp to get =real= #'s.

Lyle, you missed a very important item. That is weighing the individual axles. Pin weight goes almost 100 % on the trucks real axle.

One wants to get that rear axle weight and subtract it from the RGAWR. That number will tell you how much pin weight the truck can handle. Once hooked up a person should return to the scale and get three readings, Front and rear TV weights and the trailer axle weights. Add all three together to and compare that to the trucks combine weight rating.

Compare the TV rear axle weight to trucks RGAWR and assure the tires weight ratings add up to or exceed the RGAWR. Add the two TV axle weights and if you are in a state that licenses tonnage assure that you have purchase enough for the weight the truck is carrying.

Another consideration. Do you play in the mud, or rocky roads with your tow vehicle? IMO, singles are better in the mud,and avoid the sidewall cuts of rocks between the duals. I also want to stay below 22 feet on the TV, for some roads such as Turroweep. Just below 20 as I have now is even better for turning around, and saves money on the ferry to Newfoundland. My 5er is within all the numbers by the Cat scale, and I will not give in to bigger-itis!!!

There is nothing like the security of knowing that you have way more truck than you need especially when you go into that exit ramp a bit too hot & the box on wheels behind you feels like it wants to drive.

I have never had a SRW truck. Never had an automatic vehicle before my DRW TV. Never towed anything before my 35' 5er. Jumped right into the deep end of the pool. Sink or swim. Over 200,000 miles later, still swimming.

No, I can't zip around a carpark like I can in my little Toyota Yaris at home, but you get used to having to go out to the fat a$$ed parking 1/4 mile from the store doors.
