Newbie towing question

I recently purchased a gas 2019 F250 RWD to tow my 2018 Jayco 24.5 ckts fifth wheel. I am a newbie with heavy-duty trucks. And I have a question about steering with the fifth wheel hooked up. The two-wheel-drive version was the best choice for us because it is 3 inches shorter than the 4x4 F250 and fits under the fiver. And we aren't going anywhere we will need 4x4. The 4x4 would have been too tall and we didn't want to have to raise the trailer any further as the axles were already flipped. We just took it out for its first camping trip and it towed it like the trailer wasn't there. The trailer, loaded, has a pin weight of approximately 1,600 pounds and the truck squatted about 2 inches with the trailer on it. This is a small fifth wheel and well within the trucks specs with its payload rating, per door sticker, of 3,759 lbs and a rear GAWR of 6,340 lbs. I did notice though that the steering felt a little lighter with a tiny bit more play with the trailer on the pin versus the truck driving by itself. It didn't feel out of control or anything just a bit different.

Is that normal and to be expected? I am reluctant to add airbags to address the 2 inches of squat as that would put the trailer too nose high and be bad for the trailer axles. Are there any workarounds to shift some more weight onto the front axle or is the bit of extra play in the wheel nothing to be concerned about? Again, it was steering fine it just felt slightly different loaded than unloaded. Thanks!

2" of squat is perfectly fine. You don't want the suspension so stiff that it does not move, or you will beat everything to pieces, including yourself, going down the road.

LOCATION OF THE PIN is the elephant in the room here. That pin hanging down from the hitch of the 5th wheel trailer. Its relationship to the rear axle (i.e. ahead of, directly over, or slightly behind) determines whether you add weight, don't affect the weight, or remove weight from the front wheels.

Hitch the truck and trailer, pull them straight. Where does the pin sit with regards to the rear axle?

Do you have a slider hitch? Are you leaving it in the rear position all the time?


Thanks! To answer your question, when hitched up the pin on my fiver sitting on the hitch is directly above the rear axle.

Answer: I was talking about a truck-bed-mounted camper. Once my wife and I are ready to downsize from our fifth wheel, we have been thinking about getting a truck camper which is one of the reasons we went w/ the 2WD F250 to get some extra payload capacity. At 3,759 lbs of available payload, a rear GAWR of 6,340 lbs and a 10,000 lbs GVWR there appear to be a few of the lighter truck campers that would work though not with all the comforts of a fiver for sure.

You will find some hard wall truck campers under 9' long without slides that may keep you under tire and rim limits. My Arctic Fox 811 (9' with slide) was about 4000 lbs once filled and loaded requiring me to make some upgrades to safely roll at 11,500 lbs GVW. My short bed extended cab truck weighed 7250 lbs when outfitted with the diesel and 4WD and I was applying 7000 lbs to the rear axle with the camper loaded.

Your limiting factor for carrying a truck camper are your rear wheels and suspension - The 10.5" rear axle is rated for 9750 lbs from Visteon Sterling. Although on paper it looks like you gain payload by going with a lighter engine, the empty rear axle load is not much different between a gasser and diesel and your actual payload limit really does not increase.

I embrace my couple of inches of sag as it helps me get closer to a level tow on an otherwise nose high condition. If the truck is also going to be a daily driver, realize that there will be a price for adding the extra springs in the way of a rougher unloaded ride.

Now I know better. I stopped by a 4x4 shop this AM and they said, as I have heard from others, that it might be a good idea to put a set of "helper springs" on the rear as that could address some of the squat and make the ride feel more solid and the steering a bit more sure. Since we want to eventually get a camper once we downsize from the fiver, and special rear springs are what is included in the Ford "camper package" upgrade, it strikes me as a reasonable modification and one that isn't too expensive. Certainly won't hurt.


It won't hurt anything but keep in mind the 4x4 shop is in business to sell upgrades. 2" of squat is not a big deal and shouldn't cause any issues.

I was suggesting taking it to a repair shop to make sure nothing was broken. Your truck is more than adequate as it came from the dealer for what you are towing.

That trailer has a MORryde orbital pin box as an option. If you have this option, make sure your hitch wedge is properly installed with no slop. Don't tow without a wedge installed.

Too much goofy speculation. From what you said, everything is 100% fine.
Couple inches of sag is to be expected with a moderate load in the bed. F250s have a rather soft initial spring rate and stiffen up after that. You can add whatever you want to the back to stiffen it up more if that's your desire, won't hurt anything.
No your AT tires are not making it drive bad (save for maybe a bit of tread squirm when brand new). It will drive slightly different, lol, with a 5th wheel trailer hooked up. Some folks don't understand that.
You're good, go camping, have fun!

Gravity being what it is, a couple inches of sag when loaded is normal. I would not worry about it.

This can lead to handling issues when empty and especially with a trailer in tow or just carrying a heavy load in the bed.

Your OEM front tires may be a all season type tread which are great for handling issues vs a ATX with large lugs and large voids. They simply won't track the front tires like OEM.

Weight in the bed plus a trailer pushing the back of the truck around in hard side winds/curvy roads.......
New tires can have tread roll (sway) before their broke in....
To much or to little pressure can lead to tread roll.....

Once the tires are broke in I would play around with front and rear tire pressures.

If that doesn't help the issues then I would put the OEM tires back on the rear.
On every truck I have/had I buy a pair of wheels and have MT type tires mounted. That way I can get around in muddy worksites or out in my muddy/deep snow pastures or just to get out to a state highway (7 miles) during big s=now events.

Play with your tire air pressure some. It makes a big difference in my truck.
