Fifth wheel towing comes down to pin weight against your truck's payload. Ford plans on a king pin weight of 15 percent of the loaded trailer and Chevrolet on 15 to 25 percent. That load, plus passengers, cargo and the hitch, must fit within the payload on your truck's door label.
At a glance
- Ford's 2026 towing guide puts fifth-wheel king pin weight at 15 percent of loaded trailer weight, while Chevrolet's 2026 trailering guide gives a range of 15 to 25 percent.
- Both truck makers count king pin weight against the truck: Ford includes it in cargo weight, and Chevrolet says it cannot push the truck past its rear axle rating.
- On three 2027 Jayco Eagle floor plans, the dry hitch weight Jayco lists is already higher than 15 percent of the trailer's maximum loaded weight.
- Ford says a short pickup box gives less cab clearance, and that the truck and trailer together must clear the cab in turns up to and including 90 degrees.
Every figure in this guide was read on 22 October 2026 from a truck maker's or trailer maker's own published material. The truck-side rules come from Ford's 2026 RV and Trailer Towing Guide and Chevrolet's 2026 Trailering Guide. The trailer figures come from Grand Design's Reflection 150 Series specification table and from Jayco's 2027 Eagle and Eagle SLE floor plan pages.
No trailer was weighed or towed for this article. It shows published ratings and the arithmetic they support, so treat each result as a planning figure to confirm on a scale. The percentages in the table below are this guide's own calculations from the makers' figures, rounded to the nearest pound.
Pin weight, which Ford calls king pin weight, is the part of a fifth wheel's weight that presses down on the hitch in your truck bed. Ford's guide describes tongue load or fifth-wheel king pin weight as the amount of the trailer's weight that presses down on the trailer hitch, and calls it a critical measurement to make before towing.
The two truck makers use different planning figures:
- Ford: "For 5th-wheel trailers, king pin weight is 15% of loaded trailer weight." Ford's own example is an 11,500-pound fifth wheel, which gives a king pin weight of 1,725 pounds.
- Chevrolet: "Gooseneck or fifth-wheel kingpin weight should be 15% to 25% of the total loaded trailer weight."
For comparison, Ford uses 10 percent of loaded trailer weight for conventional trailers over 2,000 pounds. Chevrolet adds that fifth-wheel trailer kingpin loads are higher than conventional trailer tongue loads. Both percentages apply to the loaded trailer, not to the empty weight in a brochure.
Pin weight comes out of payload because the truck carries it in the bed, the same as passengers and gear. Ford defines payload as "the combined maximum allowable weight of cargo and passengers that the vehicle is designed to carry," calculated as the gross vehicle weight rating (GVWR) minus the base curb weight. Ford's guide then states: "When towing, trailer tongue load or king pin weight is also part of the Cargo Weight."
Ford's cargo weight also includes all weight added to the base curb weight, including cargo and optional equipment. Chevrolet's guide says the weight of any additional equipment and all passengers must be subtracted from the payload weight.
Payload is not the only limit. Ford tells owners to be sure the king pin weight does not cause the truck's GVWR or rear gross axle weight rating (GAWR) to be exceeded. Chevrolet says the addition of trailer kingpin weight cannot cause the vehicle to exceed its rear GAWR. The combined weight of truck and loaded trailer must also stay within the gross combination weight rating (GCWR).
The ratings that apply are on your own truck. Ford says to see the label on the doorjamb for the carrying capacity of a specific vehicle, and Chevrolet says its ratings are on the certification label on the driver door or doorframe. A brochure maximum for the model is not a figure for the truck you own.
Listed hitch weights on these eight floor plans run from 1,256 pounds to 2,455 pounds before any cargo, and the truck makers' percentages come out higher or lower depending on the floor plan. The table compares the hitch weight each maker lists with 15 and 25 percent of each trailer's GVWR, the most it may weigh loaded.
| Floor plan | GVWR | Hitch weight the maker lists | 15% and 25% of GVWR |
|---|
| Grand Design Reflection 150 Series 250ML | 9,995 lb | 1,288 lb | 1,499 lb / 2,499 lb |
| Grand Design Reflection 150 Series 260RD | 9,995 lb | 1,319 lb | 1,499 lb / 2,499 lb |
| Grand Design Reflection 150 Series 270BN | 9,995 lb | 1,256 lb | 1,499 lb / 2,499 lb |
| Grand Design Reflection 150 Series 295RL | 10,995 lb | 1,570 lb | 1,649 lb / 2,749 lb |
| Grand Design Reflection 150 Series 298BH | 10,995 lb | 1,527 lb | 1,649 lb / 2,749 lb |
| 2027 Jayco Eagle SLE 24MLE | 9,500 lb | 1,480 lb | 1,425 lb / 2,375 lb |
| 2027 Jayco Eagle 29RLC | 11,200 lb | 1,745 lb | 1,680 lb / 2,800 lb |
| 2027 Jayco Eagle 355MBQS | 15,400 lb | 2,455 lb | 2,310 lb / 3,850 lb |
The makers label their hitch figures differently. Grand Design lists "Hitch" beside an unloaded vehicle weight (UVW) of 8,220 to 9,577 pounds for these five floor plans, and its table does not give a model year. Jayco lists "Dry Hitch Weight" beside UVWs of 7,915, 9,420 and 12,775 pounds.
The results split by maker. On all five Grand Design floor plans, 15 percent of GVWR is higher than the listed hitch weight, by 79 to 243 pounds. On all three Jayco floor plans, the listed dry hitch weight is already higher than 15 percent of GVWR, by 55 to 145 pounds, before any cargo goes in.
The practical rule is to plan with the larger of the listed hitch weight and the truck maker's percentage, and to treat Chevrolet's 25 percent figure as the cautious end of the range. When you have a weight range in mind, you can browse fifth wheels and other RVs for sale on Searchshop and compare floor plans that dealers have in stock.
Checking a fifth wheel against your truck takes five steps, using the trailer's spec sheet, your truck's door label and the truck maker's towing guide for your exact configuration. The 2027 Jayco Eagle 29RLC is the example below.
- Trailer weight against the fifth-wheel tow rating. Compare the trailer's GVWR, 11,200 pounds for the 29RLC, with the fifth-wheel rating the truck maker gives for your truck's exact engine, axle, cab and bed, not the highest figure advertised for the model.
- Pick a planning pin weight. Use the larger of the listed hitch weight and the truck maker's percentage. For the 29RLC that is the 1,745-pound dry hitch weight, which is above Ford's 1,680-pound figure. Chevrolet's range runs as high as 2,800 pounds.
- Add everything else in the truck. Add every passenger, pet and item in the cab and bed, plus the hitch itself. That total plus the pin weight must fit within the payload on your truck's door label.
- Check the axle and combined ratings. The loaded truck must stay within its GVWR and rear GAWR, and the loaded truck plus the loaded trailer must stay within the GCWR.
- Weigh the loaded rig. Ford advises taking the loaded truck and trailer to a scale, and measuring actual king pin weight by disconnecting the trailer and placing only the king pin on a scale. Chevrolet says weighing the combination is the only way to be sure no rating is exceeded.
If step 3 or step 4 fails on paper, Ford's guide is direct: if either the GVWR or the rear GAWR limit is exceeded, you should go with a larger vehicle or a smaller trailer.
Truck setup for a fifth wheel starts with where the hitch sits. Ford says the receiver center line of the hitch should be mounted at least two inches forward from the rear axle of the truck chassis, which distributes king pin weight for load-carrying and sway-control performance. Chevrolet's trailering page describes a similar layout, with the hitch positioning the trailer's kingpin weight over, or slightly in front of, the truck's rear axle.
Factory prep packages vary by truck line, so check what yours has before buying a hitch. Ford offers a factory-installed fifth-wheel hitch prep package for Super Duty only, and lists it as required for its fifth-wheel and gooseneck hitch kits. Ford's own fifth-wheel hitch kit is only compatible with 8-foot beds and cannot be used with drop-in bedliners or bed mats.
Short beds leave less room between the cab and the trailer's front. Ford names 5.5-foot and 6.5-foot F-150 boxes and the 6.75-foot F-250 and F-350 box as examples, and says the truck and trailer combination must clear the cab in turns up to and including 90 degrees. Ford warns that otherwise the trailer could contact the cab during tight, low-speed turns.
Ford adds that F-150 models with a 5.5-foot box will accept a fifth-wheel hitch, but most fifth-wheel trailer designs are not compatible with them. It does not recommend fifth-wheel towing for Raptor or Lightning models. Some trailer makers design for shorter beds: Grand Design says its Reflection 150 Series has 90-degree turning radius capabilities and can be towed with many of today's half-ton and short-bed trucks. That is the maker's claim, so check the pairing against your own truck's ratings and cab clearance.
The next step is to shortlist floor plans by GVWR and planning pin weight, then hold each one against your own truck's door label, rear axle rating and fifth-wheel tow rating. Use this order:
- Already own the truck: write down its payload, rear GAWR and fifth-wheel rating first, then rule out any floor plan whose planning pin weight and passengers would exceed them.
- Buying the truck too: start from the trailer's GVWR and Chevrolet's 25 percent figure, then compare trucks using each maker's ratings in our comparison of 3/4-ton trucks.
- Still choosing a trailer type: see how the hitch, truck and price differ in fifth wheel vs travel trailer, or check bumper-pull options in our guide to half-ton towable travel trailers.

A fifth wheel puts 15 percent of its loaded weight on the truck by Ford's planning figure, and 15 to 25 percent by Chevrolet's. Ford's example is an 11,500-pound trailer with a 1,725-pound king pin weight. Among the eight floor plans in this guide, the hitch weights the makers list run from 1,256 to 2,455 pounds before cargo. The only exact figure is your own trailer on a scale.
A half-ton truck can tow some fifth wheels if the pin weight, passengers and hitch fit its payload. Grand Design markets the Reflection 150 Series as half-ton towable, and Jayco says midweight fifth wheels can be towed by half-ton trucks. Ford notes that most fifth-wheel designs are not compatible with a 5.5-foot F-150 box. Check your own truck's door label and fifth-wheel rating.
The hitch counts against payload because it is weight added to the truck. Ford's guide defines cargo weight as all weight added to the base curb weight, including cargo and optional equipment, and says king pin weight is part of it as well. Chevrolet says the weight of any additional equipment and all passengers must be subtracted from payload. Include the hitch's listed weight in your total.
An 8-foot bed is not the only option, but a shorter bed leaves less cab clearance. Ford says the truck and trailer combination must clear the cab in turns up to and including 90 degrees, and that short boxes give less clearance than long boxes. Ford's own fifth-wheel hitch kit fits only 8-foot beds. With a short bed, confirm the clearance before you buy.
