Anybody that knows virtually anything about 5th wheels knows a 17.5k RV at GW cannot be hauled by a SRW truck and stay within specs.

Also, I did the numbers for that truck before I made my post. Of course the new models have increased their GVWR and GCWR...but not enough for a 17.5k 5th wheel at max weight... we are talking SRW, not a dually.

Cargo capacity for that truck is a shade over 4000, 20% of the trailer GVWR = 3500, so any way you look at it the truck will be over GVWR of 11500 when you add everything else in the truck, such as personnel, hitch itself, cargo, add ons (bed liner, steps, tonneau, etc).


GCWR 24500 - assume truck is at GVWR of 11500 = 13000 max tow rating.

Trailer 17500 - pin weight of 3500 = 14000 RV weight to tow

Bottom line, if the RV is at its GVWR, the truck will be over both the GVWR and the GCWR.


The poster and I have been having a civil PM discussion and he states he will be well under the RV's GVWR. It that true, he'll be fine, but if he runs at max RV weight, which is common for 5th wheels, he'll be over.

As noted before on this site, max tow capacity for a 5th wheel is the GCWR minus the weight of the truck when ready to tow...do the numbers.

hooverbill,
I can tell you from experience that he will be overwieght on the truck, I have an 03 dually and a 16400gvw trailer, and I have 6600# drive weight, and 12,500# trailer axles, 4400# steer, giving the truck 11,000# and a combined of 23,500#, and I am not at my trailer gvw either. So with the gvwr of the 2 trucks being the same, there is no way that he can haul a 17,500# gvw trailer and be within his weight specs, and I will bet he is over his rear axle gawr. Those weights are cat scaled. 2 people, approx 30 gal fuel in the aux tank and approx 30 gal of fresh water in the trailer, and empty waste tanks.

FYI, the GVWR for a 2012 GMC 3500HD 4X4 Duramax SRW is 11,500 lbs and the GCWR is 24,500 lbs.

Your trailer would be within specs with a 2012 SRW 3500HD.

drfife,
No it is not ok for motorhomes to be overweight either, I know there are some that come from the factory that way, but it is not right. It puts the those in the vehicle and those around them in a dangerous situation. I said that the 2 trucks are similar, I know that my trailer would work with a swr new model, but not a trailer that weighs more, also what is the rear gawr, it should be somewheres around 6600 to 7000#, not sure exactly, but that would put it really close to over.

Guess I stand corrected here--believe I was using the GCVW of the dually. Mea Culpa.

wingnut,
mine is an 03, the gvw is lower than the newer duallys and I think it is around 13,000#, and a gcwr of somewhere around 30,000#. I think the 11,500# gvwr and 24,500# gcwr is for a new 3500 swr gm truck.

Hi

I just finished a chat with Chevrolet.

Here is the transcript.

Welcome to Chevrolet. Please wait while we find an agent to assist you...</SPAN>
16:04:00Chris:
Welcome to the chat! I am a GM Marketing Support Representative. How may I assist you today?
16:04:12Customer:Hello
16:05:34Chris:Hello. How can I help you?
16:05:56Customer:I would like to know what the gcwr and gvwr is for the 2012 silverado 3500 hd with single rear wheels crew cab long box and the duramax engine
16:06:36Chris:Thank you for coming into the chat with your question. One moment please.
16:07:24Chris:Would you prefer 2WD or 4WD?
16:07:30Customer:2wd
16:10:45Chris:Unfortunately I am not provided with the GCWR. However, the GVWR for this vehicle is 11400 pounds.
16:11:57Customer:?
16:12:23Customer:How do I get the GCWR your web site only give me the DRW weights?
16:12:50Chris:You can contact your local dealership and they may be able to assist you with that. If you would like, I can help locate a dealership for you.
16:12:54Customer:how about the maxt towing capsity fort the SRW I have described?
16:13:29Customer:do you have the max towing capacity for thie truck with a fith wheel hitch?
16:13:34Chris:This truck can tow up to 13000 pounds.
16:13:53Customer:OK thanks
16:13:59Chris:With a fifth wheel, it can tow up to 17300 pounds.



I would guess this settles the question about whether or not the truck will do the job of towing at 17,000 lb fifth wheel trailer.

Yes it does, the answer is no.

The towing capacity is the GCWR minus the weight of the truck when ready to tow...do the numbers

See post #71 above.

Hi

Post #71 has several errors. The fifth wheel hitch allows a 17,300 lbs tow. The bumper tow is the 13,000 lb figure. It is quite acceptable to load a fifth wheel trailer so you have 15% on the kingpin. This is 2,625 lbs. plenty of room for towing.

Assuming the GWR of the trailer in question is 17,500 lbs. and I back my 2012 pickup configured as described unde this 17,500 lb GWR trailer and tow it to the scales. I load my truck and trailer until I reach my GCW of the TV and insure that I haven’t exceeded any other applicable rating (tires axels etc) then what is wrong. Ok so maybe I am unable to reach 17’500 lbs on the trailer but I sure will be close.

Now further to this I rented a 45,000 lb GWR trailer locally for convenience. The trailer weighed 9,000 Lbs. I loaded an electric car (an off road vehicle) on this trailer that weighed 3,000 lbs. My total weight on the scales was 23,000 lbs for the combined unit. The TV has a 23,500 Lb GCW rating. Assuming I haven’t improperly loaded the trailer and over loaded the TV what is the problem. By the way I loaded the TV with the parts needed to repair the electric car this accounts for the weight difference if you do the math on these figures.

I own a 40 fifth wheel travel trailer built by one of the poorest builders in the nation. The GWR for the trailer is 15,900 lbs. my TV has a GCWR of 23,500 lbs. The TV weighs 7,900 lbs. do the math my GCWR limits me to only 15,600 lbs for the trailer. In reality I operate the trailer at 15,000 lbs for a total GCW of 22,900 lbs. Now tell me what is wrong with this.

If the gentleman wants to purchase a 17,500 Lb GWR trailer and operate it at 17,300 to be within the GCWR for the TV because he doesn’t like DRW I don’t see any thing wrong with this idea.

The point to the entire dissection is safety.

I would propose that a trailer designed to be operated at 17,500 lbs. and is operated at 17,300 lbs would be just as safe as when it is operated at 17,500 lbs.

So it sounds to me like the gentleman in question has done his due diligence and determined he is or has purchased the equipment to operate with the designed limits of the two vehicles IN Accordance With post #51.

I prefer the DRW and that would let him load to max all up weight for the trailer but it is my opinion that loading the trailer a few hundred pounds under the rated weight to meet your preference for SRW is quite acceptable.

You will note that all of my post advocates not exceeding weight ratings.
That term is “exceed” not “under” the weight ratings.

Looking at GMs online ordering guide shows a cc30953 '12 loaded LTZ Dmax/A 3500 SRW 2wd long bed extended cab with a 11200 GVWR with a 7050 RAWR with a 17300 lb tow rating.

Using GMs online weight calculator that figures in the truck options and std weights, shows the truck has a 4660 lb payload.

GM also shows a 3500 SRW with a 11500 GVWR GIY option and a 11600 GVWR C7V option on their 3500 SRW trucks.

The SRW fits within many 17k trailers tow vehicle needs, according to GM anyway.

You are welcome.

We are preparing to purchase an Excel and it has a 19,000 Lb GWR. We will purchase the Duramax 3500 DRW to replace our 2009 because the new truck has a GCWR of 30,500 Lbs and the 2009 has a GCWR of 23,500 Lbs.

We will also have to be careful of how we load the combined unit.

That's the whole point...you'd be over weight. I suggest you read the formula for tow capacity, it's been posted twice.

Last post on this thread, I'm done here..
