How Big of a Fifth Wheel Can I Tow
This is a question we go asked oft. You want to buy a fifth bicycle, but don't want to buy a new truck, or you have your eye on a truck and want to know if it tin handle the RV y'all want. Totally go it, so let's take a wait at how to figure this out!
With any truck, there are two numbers to be concerned with for towing: tow capacity and cargo capacity. Really, three numbers, but we'll get to that.
Towing Capacity
This number is based around the engine and transmission. Information technology's how much your truck tin can pull (and stop) safely. This number can be found in towing charts like this: www.fleet.ford.com…
To detect yours, simple google "towing charts for YEAR and MODEL".
You'll detect your model and a filigree, showing the truck style, engine, and axle ratio. Line these up and in that location's your tow chapters. Pretty simple. The reason these numbers are published in a nautical chart like this for each model yr, is they are the aforementioned number regardless of what options (besides engine and gear ratio) are installed on the truck.
For this practice, we'll await at a 2022 F350 Super Duty (6.7L Ability Stroke) SRW (Single Rear Wheel) four×4 Crew Cab viii′ Box with a 3.55 Axle Ratio. From the link to a higher place, we find this:
The number highlighted to the correct is the towing capacity, but if you run into the (4)(5) and check the notes, y'all'll come across that 18,000 is the actual capacity for a 5th wheel and 20,000 is for a gooseneck.
Note: At that place will be dissever charts for fifth-bicycle and conventional (bumper pull), so be sure to apply the correct nautical chart.
In this chart, are two numbers: towing chapters (on the right), and GCWR (Gross Combined Weight Rating), which nosotros'll touch on later. The max is 18,000lbs for 5th-wheel towing. Many people, including many truck dealers, terminate here and think this is what this truck can tow. Nevertheless, this is only half of the picture. Of equal importance is cargo capacity.
Cargo Chapters
A truck'due south cargo capacity is how much weight information technology tin actually concord in (or on) the truck itself. This number is calculated using the truck's GVWR (Gross Vehicle Weight Rating) minus the truck'southward curb weight when it left the manufactory. Since every truck coming off the factory line volition be different based on installed options, the cargo capacity is specific to each truck. This number will be found on a xanthous "Tire and Loading Data" sticker in the commuter's side door jamb and looks like this:
The sticker to a higher place is also from a 2022 F350 Super Duty SRW (Single Rear Wheel) 4×4 Crew Cab 8′ Box with 3.55 Beam Ratio. Notice that it says "the combined weight of occupants and cargo". This ways you, passengers, pets, tools, and even the fifth bicycle hitch itself (the role that mounts to the bed of the truck). Those items alone will usually business relationship for a few hundred pounds, considering almost hitches counterbalance well-nigh 100lbs lone.
Permit'south just say that it'south just a 200 lb. commuter and a 100 lb. hitch with nix else. In the example above, that leaves 3255 lbs. (3555 – 300) of truthful cargo capacity.
A fifth-wheel will have between twenty% and 25% of its total weight on the pin. That means twenty-25% sitting in the bed of your truck. The percentage will vary depending on how things are loaded, if there'southward a generator in the front bay, etc. But, it gives u.s. a range to piece of work with. Knowing this, it'due south uncomplicated math to calculate a general range of the largest 5th-wheel by multiplying your true cargo capacity by 4 for the low end (25% on the pin) and 5 for the high stop (20% on the pin).
With our example of 3255 lbs., we come up up with 13,020 – 16,275. That is the maximum size of the fifth bike. Find, the high-stop number is a LOT smaller than the eighteen,000 towing capacity! This is why cargo capacity is so of import and why most large 5th wheels need a DRW (Dual Rear Wheel / Dually) truck.
Gross Combined Weight Rating
If yous are nether your tow rating and under your cargo capacity, yous generally don't need to worry most GCWR, but you should know what it is. GCWR is only the maximum combined weight of the truck and everything connected to it or in it.
What if I add Air Numberless?
While air bags can assistance level out an over-loaded truck by jacking up the rear, it changes nothing nigh the truck's cargo rating. The truck will exist level, but still over loaded.
What about RAM and Chevy?
Yous'll detect that all of the big 3 truck makers (Ford, Dodge, Chevy) all sell as capable trucks. Option the make you like with the features you lot like, along with the correct specifications for towing and you're gold! Just be aware that RAM does make some strange combinations. When we were truck shopping, we were shown a RAM Cummins Dually with a 68RFE transmission and 3.73 axle ratio that had a great payload (cargo) capacity, but a tow rating of xviii,660. Of course, the dealer insisted it could tow a 20K fiver considering information technology's a Dually after all. ? Know your numbers, because there's a good adventure the dealer will non.
Exist Safe!
You'll run into a lot of arguing online about this topic, with references to the "tow police" whenever someone with an over-loaded truck want's to justify pulling a 20K toy hauler with a single rear wheel truck. But, every bit you tin can see, information technology's really but very simple math. That said, I've seen some pretty impressive numbers on the 2022 Ford SRW trucks that put information technology into the 18K range for fiver capacity. Merely, know your numbers. Y'all are the one responsible for your family's safety on the road. Exist safety!
