Need Help!!!

Have a 2014 Ford 250 6.7 diesel. Was seriously thinking about purchasing a Carbon 357 but have figured out its just too big for our truck. We cannot afford nor desire a bigger truck. Asking now about the 337. Its quite a bit smaller and less overall gross and hitch weight. Any feedback?

The human weight computers will be along soon. Go to your truck and write down everything on the plate on the door like the weight stuff. Then get the specs on the camper you are interested in; pin weight and gross weight, etc. The folks who work these numbers will be able to give you an idea if your truck is up to snuff. Also will want to know the axle ratio, bed length and what model F250... crew cab, regular cab and the like. It is a pretty complicated issue unless the truck is way insufficient for the towing and then a quicker answer will come. Good luck! You did good to ask before buying the trailer and NOT asking a salesman bwhahahaha

Assuming your truck is an XLT or more expensive and a SuperCab or CrewCab, your payload is somewhere between 1900-2300 pounds. This is due to the "GVW max" of 10,000 pounds for all F250 trucks. Some argue that is "documentary only" (paperwork) some say the F250 is really a F350 with a different sticker, some say.... <fill in the blank>...

That really doesn't make much difference if you're going to follow Ford's payload limitations. The empty 357 pin weight is 3060 and the 337 pin weight is 2755. Most people who own toyhaulers indicate that with the garage filled with their toys, they offset about 200-300 pounds of pin weight. Assuming you tow and load your trailer similar to their experiences, unless you travel alone (nothing/nobody in the truck cab and the bed empty) you're going to be "at or above" your F250 maximum payload and probably also at or above your maximum F250 GVW.

Now, if you ignore the F250 GVW and consider your truck is really a rebadged F350 in disguise.... Well.....

we do have Ride Right airshocks in our 250. I just cant imagine this truck not being able to handle the 337. It weighs 11700 pounds and the hitch weight is 2755.
Direct from Ford Tech dept, the numbers are 15900 and 3250. So that looks like its well within the tolerable limits. I understand that adding a generator and hydraulics will increase the hitch weight, but with cargo in the rear garage that seems to me that it will take some of the load off the front end.

Forget the "Ford tech dept." - they are clueless about your specific truck. Look at the placards inside the driver's door for the gawr of each axle, total gvwr and payload. THAT is what your truck weight limits will be, not generic numbers in a best case scenario. You can also forget the "max tow rating"; the other numbers will tell you what that will be and you will max out your payload and/or gawr before you ever get to that number in most cases, especially with a diesel 250. John has pretty much told you, optimistically, where you will probably end up. The Ride Right airshocks have no bearing on your weight limitations - they just help keep the load level....that's it.

Well they looked at the VIN number and got specific info about the truck. And John sent numbers that are in our wheel house, so not sure you what you mean

So are you saying the 337 is still too big? I understand your point, but I dont understand why I have seen so many 250s towing toy haulers like this and say they have no problems.

Wow that's a heavy towball.

I'd move the axle forward if possible.

I shoot for 12% max, 8% ideally.

Carbon 337 is a 5th wheel toy hauler. It's usually 15% to 25% for fifth wheels and gooseneck trailers isn't it? Either way, just used 23% because that was what they used for the published dry hitch weight ... 2755 / 11925 = 23% ... using same percentage for (fully) loaded hitch weight is 16755 * 23% = 3850.

Well i appreciate all the feedback, but now we are totally confused. It seems like we get a different answer from every person we ask. The fact of the matter is we see 250s towing 5th wheel toy haulers all the time and cant figure out why this is so difficult to figure out.
Im to the point now where Im about to just say forget it!

The speed limit on M-32 from our house to Gaylord is 55MPH. The fact is that when driving that speed I get passed by everything from "grandma's in Escapes" to 18 wheelers in the left lane.... I can't figure out why they all are "OK driving faster than the speed limit"..... Same argument you're making. THAT STILL DON'T MAKE IT RIGHT FOR YOU TO IGNORE THE NUMBERS..... If you choose to do so, nobody here will stop you (physically) from buying or towing any trailer you choose. But, you did ask for "numbers to validate whether it's OK or not. The numbers, both from your truck's door post (not some VIN generated website) indicate the true capacity of your vehicle as Ford built it. The numbers from the Keystone website for both trailers that interest you give pin weights greater than Ford certified your truck to carry.

What you do with that information is entirely up to you. And, if you read the notice (actually a warning) on the RideRite Air Shocks installation instructions, it states that their product DOES NOT increase payload or GVW. YMMV

Lisa B and others, the link in this post below is a video about how all the weights work together and is excellent. It'll explain about what most critical numbers are and how they reduce some numbers given in the brochures. Well worth the watch. It is also put out by a group that is only interested in RV safety. Well worth the watch and eliminates gut feelings and opinions from decisions. After all, every ones safety is utmost on our minds. https://rvsafety.com/rv-education/ma...ks-to-trailers

I have 2700 lb hitch weight toyhualer its over the yellow sticker 1200 lbs on the truck with a13 2500 duramax . The weak point was the 20 inch tires and springs . I went up to 3600 load range tires and 18 inch rims and installed air bags that along improved the performance and control of the 23300 lb rig. Even with my new 1 ton Denali very close to all the weights on the yellow tag but I'm over GCWR 23400 for the under rated GMC 1 ton combinations weight . I have a question say trailer weight is 16 k loaded the truck takes 25 percent I'm seeing axle weight on cat scale of 12 k lbs . How is the16 k lb trailer weight figured?

Lisa B...


Here's the deal...


There are rules, laws or customs in just about every state in the union and most likely throughout North America in total that limit an F250 to 10,000 pounds GVWR..


Now, if you are of majority age; you can choose to ignore those rules, laws or customs or not... That as an adult is solely your choice...


Just accept that eventually the law and/or fate may well choose to punish you for your choice to ignore..

Also, here's another consideration. If you choose to ignore the stickers based on the notion that "other people do it without any apparent problems" and, God forbid, you have an accident, the insurance company is going to tell you to "Take a hike".

What do you mean by this? They won't pay the claim or they won't renew?

I think it would depend on the language in the insured's responsibility section of their contract. Could mean either, neither or both.
