Fifth Wheel towing wF250SD diesel.

Fifth Wheel towing wit 2017 F250 SD 6.7diesel, w/ tow package.

Anyone towing a OF373RBS Open Range by Highland Ridge with F250SD 6.7 PowerStroke FX4 off road w/ tow package?

The factory literature say 16K for weight, but on two models we have seen the important manf sticker says they were in the 12.5K range.

So any experience or insight here? I'm new to 5th wheel towing, weights and setups.

When towing a 5th wheel the single number to look at first is the cargo capacity of the truck, since in most cases this is the number that will be exceeded first. So I would start by looking at the dry hitch weight of the 5th wheel, add to that 25% of the carrying capacity of the 5th wheel. That will be the true hitch weight of the 5th wheel when fully loaded to capacity. Remember the cargo capacity of the truck per the sticker is the OEM weight plus a 150 pounds driver and full fuel tanks. So every pound you add to the truck over that also counts against the cargo capacity.

Similar to clr’s thought, I’d take the trailer’s unloaded sticker weight and add at least 1000#, then take at least 20% of the total. That’ll give you an assumed pin weight.

A 3/4 ton with a Diesel engine will have a lower payload number to work with. If you want to stay under the truck’s GVWR you’ll need to do these calculations.

The Diesel engine will have no problem pulling the weight so that’s not an issue. The thing to check is can the truck carry the weight.

Dry weight weight of the trailer number is close to useless. After gear is added the specs put it at about 16K (dry 12.6K nothing in it) I would go by the 16K.

Sorry I am a little confused as to the numbers that you are stating......... but if the yellow sticker says 12.5K then you need to add 1k to 2K or more for water, propane, gear, supplies etc.

The driver's weight is NOT a part of the Payload Capacity equation, it's a part of the Towing Capacity equation.

Payload Capacity considers the driver as one of the Occupants. It only exempts the weight of the full fuel tank.
Towing Capacity exempts the weight of the full tank AND a 150lb driver.
That's why the payload sticker says "Occupants and cargo should not exceed xxxxlbs".
rlh, you need to focus about the trailer's pin weight. The trailer's weight is secondary to that.
You'll always run out of payload capacity WAY before getting close to towing capacity.

By the way, we also found a Open Range that's perfect for us, if we ever decide to go bigger.

I have the F-350 and Open Range RES347 that is 14,000 plus gross weight and the pin weight is over 2000. Andersen hitch is 35 pounds which also saves weight. Another issue I had to change the rear truck axle blocks to lower the truck 2 inches to help level the RV. The 350 is needed to keep within limits.

Unfortunately, the F250 diesel has a fairly low payload capacity. The GVWR of this truck is likely 9900 lbs or 10000 lbs. Ounce you will have the weight your FW puts on your truck, weigh your truck on a truck scale with the passenger and your hitch in the truck. The difference between your sticker weight (10000 lbs) minus your truck weight will give you the available payload for your FW.
Your truck is a 2017, and is lighter than mine, but not by a lot. I changed my F250 for a F350 when I realized I was at least 500 lbs + overweight in payload...and we have to be careful because the Ford F 350 (2017 +) has an option for a 9900 lbs GVWR truck, you have to look for the GVWR of 11500 lbs. This is what I have, and It gives me close to 3000 lbs of payload capacity for my FW.

I had a F 250 and upgraded to a F 350 to get my weights in line. I have a pin weight of 3200 lbs fully loaded well within my CCC on the truck. I towed a 1900 lb pin weight Rockwood with a F 150 had CCC of 1850, adding truck load it was 800 lb over weight. Never again.

I have a 2017 F250 similar to yours....mine is an XL/STX and, according to the yellow sticker, has about 2600 lbs of payload. I also have the 3.31 gears.

We have a 371MBH which (according to the mfr website) weighs about the same as the 373. Towed it like a dream. Our first trip home was about 100 miles over some mild hills, and the truck kept 6th gear most of the time. Stability was good, and the truck didn't squat hardly at all. In fact, the truck sat level with this load with about 6-7" of space between the bed and the nose of the camper. I ran down the road at 65 (with a side wind) and it was a relaxed experience.

The weight police will surely chime in, but I'm adding airbags this weekend because I know my pin weight will go up now that it's loaded. The weak link in the F250 are the rear springs....the rest of the truck is the same as the F350. While adding airbags don't change the legal rating of the truck, as long as you drive like a sane person, I bet you will be alright.

The F-350 and the F-250 have completely different rear axles. I think there is almost 1000 pounds of added capacity just in the rear axle. People do not buy the F-350 for the badges on the fender.
