2012 F-350 6.7 SB help

[Tundra]

Ok I'm sure someone can tell me what we can tow with this truck..at least I hope so.

2012 F-350 SD with 6.7 diesel engine
Short-Bed
4X4
Crew Cab
and here's the kicker it has the 3.73 axle
We purchased this truck for towing our fifth wheel and never had to worry about the weight because our unit was well under the weights for this truck.
Now we have a new Bayhill that the GVWR is 15,500 and looking at the original weight for the truck we will be right at the limits.

Looking at verious websites for towing guides they DO NOT show the weights for our truck combination of diesel engine, Short-Bed, crewcab, 4x4 with a 373 axle with tow haul.

Help would be greatly appreciated.

with your current trailer i wouldn't give it a second thought. will easily handle it. various web. sites don't always give you what you want or need. if you really want to know go to your local ford dealer and they should be able to give you the specs. and specifics of your exact truck, then take your trailer specs. and you will have your formula.

You will have a minimum of 3,100# pin weight and as much as 3,800#. So you need to weigh your rear axle fully loaded with fuel, hitch, tool box, bodies etc and compare that to what your two rear tires are rated for.

You will for sure need air bags to level out the truck.

Personally that is Dually territory for a completely solid ride.

We pull a DRV with an '09 F350. We are 7k on the rear axle, (max capacity) slightly under on the front, 23.5k gross (max capacity) and about 8-900lbs over on the GVW of the truck at (11.4k rated). Our truck handles it fine, but we do not full time, and never carry water. Our pin weight is around 3.5k. So although our truck gets it there and gets it home, we are looking for a dually. Our DRV as loaded would be around 14.5k

No, you'll probably be overloaded over the GVWR of your truck.

Looking at verious websites for towing guides they DO NOT show the weights for our truck combination of diesel engine, Short-Bed, crewcab, 4x4 with a 373 axle with tow haul.

Assuming your truck has single rear wheels (SRW), that combination was not available from the factory. Ford offered the 3.73 axle ratio only in a dually, and your pickup with the shorty bed is an SRW. (A shorty dually was not available in 2012 model year). So if you have a 3.73 axle ratio, someone changed it after Ford built the truck. Or if you have a dually axle, someone swapped it out for the SRW axle that came on the truck.

3.31 was the standard ratio for a 2012 F-350 SRW, and 3.55 came with some optional packages. But 3.31 and 3.55 ratios have the same GCWR of 23,500, and tow ratings of 15,700.

So your truck has the power and torque to PULL your 15.5k trailer, but you'll probably exceed the 11,500 GVWR if you haul anything in the truck besides a 5er hitch and skinny driver.

I think the GVWR of that truck is either 11,300 or 11,500lbs. It will be on the door sticker. The truck probably weighs 7,500lbs. So that means you can carry approx. 4,000lbs of stuff. Add you, wife, dogs, 5th wheel hitch plus weight of the 5th wheel. As you can see you may be over the GVWR. Either way it is very close.

Close. CrewCab 4x4 with either bed had 11,500 GVWR with 18" tires and 11,200 GVWR with 17" tires. Lariat and King Ranch had standard 18" tires, and 18" tires were optional on XL and XLT trim levels. So I assumed that everyone with a personal CrewCab 4x4 towing machine would have 18" tires. Only if you're stuck with fleet or "work truck" trim would you have 17" tires and less than 11,500 GVWR.

Update..

Went to Ford dealer and asked them to pull the vin# on their system. Came back as having trailer tow package and the Axle is 3.55 not 3.73 as the websites keep coming back with.
Door jam has GVWR of 11,200 with original equipment. The stock tires were 17 but we upgraded them to 18s. Also added airbags with on board compressor. New trailer is a rear kitchen, so it will have a lighter pin weight, and we don't carry other than many 5 gallons of fresh water in holding tank.
Truck weighs right at 8,000 lbs with both of us, full tank of diesel, and hitch in bed.
Only thing missing was the dogs and combined weight of them is 110lbs.

So are my thoughts are ,, 11,200 gvwr - 8,110 truck fully loaded leaves us. 3,090 for pin weight.
So if trailer is 15,500 maxed and assuming that the pin could be 15% because it's carrying the most weight in the rear kitchen then pin could be as low as 2,325 lbs.
At 20% pin that comes out to 3,100 lbs.

So we are within the weights, just barely I know, with upgraded tires and airbags IF we maxed out the trailer weight. So how many of you truly are maxed out on the trailer weight?
If maxed out, what would you do, too get back under acceptable safe weights?

Sorry your math does not quite work. The BOTTOM line is pin is what is left when subtracting actual loaded ready to go rear axle weight from rear axle rating. 20% is a very realistic rear kitchen number, 25% is more realistic on other models. 5er's transfer very little weight to the front axle!

Bad assumption. 5ers with GVWR less than about 8,000 pounds might have 16% or 17% pin weight, but heavy rascals with 15k+ GVWR will have at least 17% and probably 18% to 20%. Luxury 5ers often have as much as 24% pin weight when wet and loaded for bear.

At 20% pin that comes out to 3,100 lbs.

Count on that until a CAT scale of the wet and loaded rig proves it wrong.

So how many of you truly are maxed out on the trailer weight?

No longer, because my current TT has GVWR of 5,600 but the gross wet and loaded trailer weight on a long trip back east was only 4,870. But for years I towed a 5er with 7,900 GVWR and grossed over 8,000 GVW for the trailer.

If maxed out, what would you do, too get back under acceptable safe weights?

Empty holding tanks, minimum tools in the tool box, leave the jacks at home and hope you don't have a flat on the trailer, Max PSI in the trailer tires and the rear truck tires. Paper plates and plastic cups/glasses, plastic knives/forks/spoons, lightweight aluminum cookware. No campfire wood, no charcoal, minimum canned goods. Only current season clothing and linens. Move heavy item to the back of the trailer to reduce pin weight. If your headlights still blind oncoming traffic at night, then add air bags to the rear suspension to bring the headlights back down to earth. And drive extremely carefully.
