Even if a trailer is within the Rated Maximum Tow Capacity the rig needs to meet additional specifications. Most notable in this case Cargo Capacity (plus axle weights, tire loading...).

OP, I'd guess the trailer weights you are quoting are from the manufacturer, which are routinely inaccurate and overwhelmingly on the low side.

Regardless of weight that 5th wheel is probably 35 ft or longer which makes for a lot of area for the wind to catch. Even if it is in your trucks capacity a dually would tow it more comfortably due to the extra stability it provides.

The high capacity tow package on the F250 required 20" wheels and 3.55 gears. If you have 3.31 years you don't have the high capacity tow package. The high capacity package also would have given your truck the M275 axle in which case there is no gear sets available over 3.55 stock or aftermarket.

OK. What’s your truck’s cab- and bed configuration. IOW, what’s your truck’s wheelbase? 4x2 or 4x4? Which wheels (18”? 20l”?) and tires (all season or all terrain)?

Regards,
Jim/ crewzer

elprofesor86, do you actually own the 5th wheel or which one are you thinking about? Someone here might have it already and can give you better weight #s than the brochure claims.

I realize this doesn't change Ford's manufacturer's recommendations/guidelines but it basically turns my truck into an F350 with 3.73's. Has anyone done this or what are your thoughts?
i expect you will exceed your truck’s payload by a significant margin.

I tow a 13,995 5th wheel with a F350 diesel and I’m right at my 3523 lb max payload. What is the never exceed cargo rating on your yellow door sticker. It’s probably only in the 2200-2300 lb range.

2019 Montana 3730fl_ 40' with 6 slides is a lot of trailer and would be surprised it actually weighs what the brochure claims. Remember they're not counting all the bling that was added during the build process, then add all your possessions (amazing how the little things add up quick).

Maybe take your F250 to a truck stop or somewhere that has public scale and weigh it. Full fuel tank, passenger's and any misc items you might be carrying. This will give you a starting point and surprise you how much actual cargo weight (pin weight) you have.

I personally wouldn't pull that with a F250. You could be setting yourself up for a stressful towing experience.

you are (unfortunately) another example where salesmen/ proud internet users have seriously led you astray.

To safely pull a (16K# +) load you need a 3.10 dually F350, with a payload rating of of 14K.

To be somewhat within your current specs you shouldn't exceed (a carefully loaded) 10K pound fifth wheel.
X2^^. You will be over payload and at the edge of the safety envelope. Please don't drive on the same roads as me and my family.

That 2670 lb "pin weight"......not tongue weight....is the approx. pin weight of the trailer totally unloaded, as it was built at the factory. The pin weight will NEVER be that light in real life use......unless you plan on using your trailer with nothing in it.....no food, no clothing, no cooking utensils, no NOTHING. So, let get to the REAL number you are going to encounter. Let's say you end up with 15,500 lbs of trailer weight....GVW, as verified by using a CAT or similar scale. Pin weights will normally be in the 20-25% of the GVW......what the trailer actually weighs. So do the math....20% = 3100 lbs. 25% = 3875 lbs. And I haven't even added in the weight of the 5ver hitch, approx. 175-200 lbs......so now you could potentially be knocking on the door of 4000 lbs. Also, what about passengers, tools, toolbox, extra fuel, firewood.....anything and everything that goes in or on the truck will cound against your payload numbers.....and you are already overloading it BEFORE you add up all that stuff, with the pin weight and the hitch. I can absolutely GUARANTEE you that you do not have 3875 lbs of payload capacity with your F250 Diesel truck. If you are really interested in what your payload capacity is, in real life, open the driver side door and check the white/yellow highlighted placard that is located on the door post. There you will find the Payload/Cargo Carrying Capacity of the truck you are driving.......not brochure numbers that aren't real world stuff unless you just bought a totally stripped down regular cab, gas motor, 2WD, XL truck......and I'm pretty sure you didn't.

Towing a 5ver of that kind of weight will tax, and possibly overload a F350 that is a fairly loaded up truck. A trailer that size needs waaaay more than an F250. If you have the "average" F250 Diesel that is out there on the road....4x4, CrewCab, Lariat trim, I'd be surprised if you have 2300-2400 lbs of payload capacity. My previous truck, like the one I just describe except it was an XLT, not a Lariat, had exactly 2148 lbs of payload capacity......and a Lariat would have just a little less because there is more "stuff" on it, which subtracts from the available payload.

Man that would scare me at those weights to tow. I'm in a 2011 F-250 6.2L CCLB FX4 Lariat and it tops out at 2546lbs payload.

The diesel version must be really low in my year range.

Just believe the experts here. Weigh that thing, weigh your truck. Do the math. And don't forget: Those rules and ratings are there for a reason. Yes, any truck can get your trailer in motion. The question is, can it do that safely and up a hill?

Three days since the original poster has spoken; I wonder if he now believes us - OR the salesmen that told him it'd be OK.
At least he has been forewarned.

PAYLOAD, PAYLOAD, PAYLOAD!! A F250 Diesel will NOT have enough payload for anything over a 10,000 5th wheel.

I had a F150XLT with 1964 lbs of payload tank was looking at F250s for more payload. Several F250 diesels had less payload than my F150XLT..

Here are some pictures of F250 diesel trucks I looked at.

A F250 Platinum CCSB 1972 lbs of Payload




A F250 Lariat CCSB Diesel, 2291 lbs of Payload



This is what bought (2017 F350 Lariat CCSB Diesel) to barely legally tow a 13,995 gross weight 5th wheel.
3500 lbs Payload

I was in the same boat when I had a 2011 F250 CrewCab, Diesel, 4x4, XLT. Payload.....2148 lbs! An F250 for a trailer that size is absolutely ludicrous! It's overloaded in probably almost EVERY category of weight capacities and is a danger to everyone around it while being towed.
