Looking at some keystone cougar 5ers and trying to figure the pin weights.

My 2012 F250 KR 6.7 (de-rated to 10k gvwr, fawr 5200lb, rawr 6100lb) says I have 2046 lb cargo. Seems lite does de-rating lower this? Anyway hitch 200lb+DW+DS+me = 650 = only ~1400 left for pin weight?

The unit i like is cougar 324rlb has pin weight of 1530lb. Well that won't work. My question is that weight the max pin weight including cargo in trailer or not? I assume it dry pin weight, but you know hoping

If not I'm guessing another 150-200 extra pin weight extra added from 1000-1200 of cargo.

Nothing will fix the tag on the door, but what can i do to overcome the difference? Thinking air bags might get me over the hump, but I still won't be legal by the #'s.

I see much bigger trailers with less capable trucks going down the road and i am wondering how they are doing it!

Of course the salesman says I can tow two of them at the same time!

Maybe weigh at a scale and minus from the fawr+rawr to find real cargo rating?

Whatever the door tag says is the cargo/payload limit. Air bags don't add capacity to the cargo limit. Anything/Everything added inside the 5vr would add to the pin weight.

Unfortunately, you have found the problem with having a very heavy truck with heavy diesel engine, 4wd, crew cab and King Ranch option package, which all add weight to the truck, which is subtracted from the GVWR to derive the payload capacity.

Yes, take the truck to a scale and weigh it. Also weigh each axle separately. Subtract those weights from GVWR, FGAWR and RGAWR and you will find the actual payload capacity for your truck. Although, Ford already put the yellow payload sticker on your truck, which should be reasonably accurate.

You'll likely find the front axle weighs a little less than 4500 lbs, the rear a little over 3000 lbs and whole truck about 7500 lbs, with no passengers. 10,000 - 7500 = 2500 lbs payload. 2500 - 650 for passengers = 1850. Subtract 200 lbs for the fifth wheel hitch = 1650. That's what's left over for the loaded trailer's pin weight, which will be more than the advertised dry pin weight, obviously.

These are the things the salesman doesn't tell you when you buy a diesel crew cab 4wd F250 loaded with options. The truck is a tank.

With Ford that derated 10K number is just a legal fiction to keep the truck under limits in some states. The actual capacity is untouched.

I see you have a 2012 f350. Same color as me btw! The 250's and 350's list out the same in the towing guide. We both have the 4x4 KR. Your trailer lists a pin of ~2k. Do you mind me asking what your cargo tag says? I'd assume you have more, but wondering how much.

Well those #'s would be great! 2500lb - DW+DS+ME = 400 + Hitch(250) = 1850lb. The coach has dry pin of 1530lb + 200lb extra leaves 120lb. Not much room, but a little.

I guess weighing is really only way to know. Might have to stay TT though I was hoping to make the jump!

Well that was certainly harsh, but true.
I really don't understand the 10 GVWR pillar tag, or still making a 25 series truck for that matter. Why can't Detroit just offer a grocery getter 1500, a hefty 2500 SRW and then the bigger payload 3500 DRW? This question only creates confusion to new truck owners and seasoned vets alike.
Many folks ingnore GVWR OP and run by the RAWR which should be about 6k lbs for your truck. Subtract unladen weight and that's it for payload. Unless your truck is just a stud like many I read about here

On edit OP
After reading your last post don't give up. You can easily go by your tire ratings and if that's not enough you can replace tire/ wheels with higher rated ones. Might need to add air bags or springs but your truck will work with that 5er.

I agree. It would be FAR simpler to do this.

Just checked my door post. I have a 06,Diesel, f350 sb/cc/srw with factory 20 wheels with E rated tires. 11,400 lbs GVWR
FAWR 5600 lbs,RAWR 6900 lbs and a cargo capacity of 3676 lbs.

You can ignore the GVWR and go by just the RGAWR, but with only 6100 RGAWR, you'll only be picking up maybe 500 lbs of payload capacity, since the empty rear axle weight should be about 3200 lbs for a short bed crew cab diesel.
