Safe Pin weights

Looking for opinions on the following setup.
TV '17 F-250 6.7L turbo diesel, SRW, EC, SB, 5th wheel tow capacity 16,200 CCC of 3030lbs.
5er, Sprinter 3340fwfls, 37' dry weight 10,140, CCC 3560#, GVW 14,000#
I am calculating my CCC at around 2000# ( on the high side). That would put the 5er at around 12,140 GVW give or take a few pounds. Is 15% a normal number to start with in calculating pin weight? At 15% that would be a pin weight of 1,821#
Is that a safe number for this truck? I really do not want to go much above that 1,281. would that be Ok for a SRW TV?
Thanks, in advance.

Normal pin is between 15% to 25% of 5er GVW, at 12,140# for GVW then 15% is 1,821#, BUT with that light of pin chucking is highly likely most figure between 20% and 22% to get away from chucking. That would put you between 2,428# and 2,670#. Depending on what you load into the TV for camping, you may exceed the 10,000# GVWR of your TV.

You should always use the RVs GVWR as where to calculate your pin weight from. I would use at least 18% of the GVWR to figure how much you would/could have on your truck.

Afrnd2all,

The one specific number you left out of your post is the yellow door sticker on your truck. That payload number, if your truck is a Lariat, is probably about 2100 pounds. Given 500 pounds of passengers and cargo in the truck and a 150 pound fifth wheel hitch, that only leaves around 1450 pounds for your pin weight.

Using your trailer weight figure of 12140, at 15% pin weight you're on track with 1821, about 371 pounds over your truck GVW. If you consider that you could be closer to 25% pin weight, that would be 3035 pounds, or closer to 1585, more than double the remaining payload of your truck with passengers, cargo and hitch.

That trailer is much better suited to a F350 and will very likely be "over GVW" for any model F250 with a diesel engine.

Yellow sticker is passengers and cargo not to exceed 3026#. TV is rated at 10K GVW.

According to the Ford website, the base curb weight for a 6.7L F250 SuperCab short bed XL (base model) 4x4 is 7156. Any optional equipment will add to the "base curb weight". With a 10K GVW, that leaves 2844 payload. If you have an XLT, the curb weight goes up/payload goes down. It's even more critical with a Lariat, King Ranch, Platinum model.

Do you own the truck or are you considering buying it? That payload doesn't agree with anything Ford has published in their specifications on the SuperDuty.

Hey John, he may not have a 4x4 truck. If he does though, I'd have to agree with you. I know from personal experience how puny the payload capacity is on a F250 4x4 CC Diesel....even the XLT....which is what my previous one was.

And I do realize that he has an extended cab, not a crew cab

Thanks, in advance.
A good/fairly accurate number to plug in for a 5ver is to calculate 20% of your GVWR of the trailing when figuring pin weight. So in your scenario, GVWR = 14K. Let's say you only load it to the 13K weight. So 13K times 20% equals 2600 lbs. Add in another 175 for the hitch and you are at 2775 lbs......might as well say 2800 lbs. Keep in mind, in late model truck's like yours, even the driver's weight has to be deducted from the available payload. So when you figure driver's weight, passenger(s) weight, any additional stuff you put in or on the truck....everything, you will most likely be over the payload capacity. 3026 - 2800 only leaves you 226 lbs for driver, passenger, and everything else.

I do currently own the truck. Its an XLT 4x2. Here is pic of door sticker.
Reason for the original question. My wife and I are trying to choose between a Sprinter 298fwrls or the 3340fwfls. Thanks again.

Thanks for posting the pic of the yellow/white payload sticker. Did you see/read my explanation above ^^^^^. Just curious what the GVWR is on the other trailer you are looking at? The 3340FWFLS is just too much trailer for your truck. Hopefully the other one is smaller/lighter weight.

I looked up the Sprinter 298fwrls and the GVWR on that one puts you at 12,260 lbs. So using that 20% number again and then adding hitch weight, you would be at approx. 2627 lbs. That would still only give you 400 lbs for Driver, passenger(s), and everything else that you put in or on the truck....not much wiggle room there either.

I tow a Cougar XLite 27RKS that weighs about 9100 pounds when ready to camp. The specs on it are Dry Weight: 7136, CCC: 2864, Empty pin: 1230. When ready to camp, the pin is much closer to 1800 pounds and my truck is "at it's max" GVW. I have never felt that there was a lack of power, or a need to worry about towing. But, if I tried to tow a trailer that was any larger than what I have, there's no way I could keep my truck under the GVW. Possibly I could "convince myself" that I was OK by saying I was under the RAWR or that my tires were not overloaded or ????? But no way possible to tow my 10,000 pound GVW trailer with my 10,000 pound GVW truck and not be "at the brink" of GVW.

I'll go out on a limb here and say that there's no way you can stay under your GVW with either of those trailers. Not with your current truck.

I just have to say that my truck has a payload of 3190 if I recall and I would not put either of those trailers on it. You need a one ton for that big of a trailer. Anything with a tongue weight of 2500 or more should go on a one ton IMO. Of course, we could go back to the "it will pull it " deal but that doesn't make the numbers work. It's the same old thing we all face from time to time; bigger truck or smaller trailer to stay within the limits.

Thanks to all of you for the feedback. It honestly is helping me figure this all out.
Have much to rethink. My wife and I were just looking for a trailer we could be comfortable in for a month or so at a time. The 334fwfls was nice but a bit out of our price range. The Sprinter 298 was the one we had our eye on. Not so much now. Again, thanks for your help

I think you are close to making your F-250 work. Load your truck as you normally would and get it weighed. Select the hitch of your choice and get a shipping weight. From there you can calculate the available Pin weight, I would think you have about 2350 Lbs available. That's a lot. To me it equates to a 10 to 11K loaded fifth wheel

Now, find a unit you like and request a actual pin weight weigh slip. Now let the boys argue the change when loaded.

Remember, you may have to be conservative in your loading habits, No generator or washer dryer and traveling with near empty tanks. The absence of a slide in the front bedroom really helps with the pin weight. My fresh water tank is at the rear of the unit and actually takes weight off the pin.

Most 4x4 350's only have 3500 CCC available.

X2!
You are close, you have a large payload for a 2500 diesel. You may be towing at within a few pounds of your GVWR -/+, but should be maybe a little under.
