How do I Improve Ride Comfort When Towing a 39' Travel Trailer with a 2025 F-350?  

Updated 02/09/2026 | Published 02/01/2026

Question:

What is your recommendation suspension upgrade for towing a 39’ travel trailer bumper hitch with sway bars ? I’d like to take the strain off the stock suspension and make the ride more comfortable. 2025 Ford F350 SD crew cab long bed platinum

Hello Robert,

It sounds like you may be experiencing a bit of white-knuckle towing, which is never enjoyable. When a trailer doesn’t want to track straight, it can make every mile feel longer than it should.

I do recommend a weight distribution system, but the key to choosing the correct one is knowing your total loaded tongue weight. A 39-foot pull-behind travel trailer will typically have a loaded weight somewhere in the 10,000 to 14,000 lb range. Your tongue weight should fall between 10 to 15 percent of that loaded trailer weight. When tongue weight is outside that range, stability can suffer, which often shows up as sway and an uncomfortable towing experience.

Since you have the long bed truck, a great option would be the Blue Ox SwayPro Weight Distribution with Sway Control for a 2-1/2 inch hitch, rated for 15,000 lbs GTW and 1,500 lbs TW # BLU54TR. This setup would be a solid choice if your loaded tongue weight is close to 1,500 lbs.

I want to make sure we get you into the system that works best for your exact setup. The most accurate way to do that is by measuring your loaded tongue weight. Some people use a tongue weight scale like # BTBRV27FR, but most folks do not have one on hand, so a CAT scale works great.

To find your loaded tongue weight, load the trailer exactly as you would for travel with propane full, batteries installed, gear loaded, and your normal water level. At a CAT scale, weigh only the truck by itself. Then hook up the trailer and weigh only the truck again, keeping the trailer axles off the scale. The difference between those two truck weights is your actual loaded tongue weight.

Once you have that number, please let me know so I can confirm whether the Blue Ox SwayPro # BLU54TR is the best option for you or if we should look at a different rating. I look forward to hearing back from you.

I have a 2022 F250 short bed with the Air Lift system, I pull a 36’ bumper pull. The Blue Ox hitch takes the bounce out, work ok and a lot easier to set up and use than the Equal I zer hitch I used to have. I wished I had tried the BW hitch but wasn’t sure about it.

@Bill Thanks for the response, Bill, and I’m really glad you mentioned the B&W Continuum Weight Distribution System w/ Sway Control for a 2.5" hitch 16K GTW, 1.6K TW, # BW28FR. This system truly is impressive. The build quality, smooth ride, and integrated sway control really set it apart, and it’s clear B&W put a lot of thought into both performance and ease of use. This would work great for you Robert! It is not as cost effective as the first option, but you can never go wrong with the B&W name. Bill if you ever end up getting a new system, this would not disappoint.

Have used the Blue Ox hitch for 2 years over 12K miles. It is easy to install and set up. Hitching the trailer is easy too, just lock the tongue closed on hitch ball and raise the trailer/vehicle a bit using the jack stand. This takes a lot of spring out of the bars and makes them easy to engage. Do the same thing prior to disengaging the bars. Wear gloves for this process and it is safe. Have used the Blue Ox exclusively to pull a 37 Toy Hauler with empty weight of 10,800 lb. Has 100 gallon fresh water tank can easily be closer to 12, 000 lb. Tongue weight is 1100-1200 lb. The trailer pulls good with no significant sway in everything but the worst cross winds (i.e. over 35-40 mph). On windy days especially, I might also notice a slight pull from a passing truck, but this is actually pretty rare. Truck is 2021 Chevy 3500 crew cab, long box. I did add TorkLift Stabile Rides on upper and lower overloads in the rear. I put on the TorkLift hardware because that truck sometimes carries a truck camper instead of the trailer. But I think it helps any time you are really loaded. When unloaded, I essentially have factory suspension and ride. Overall a very good experience. In the north US winter highways are bumpy due to buckling right now ... those are going to be rough no matter what. My buddy has air bags with a similar rig and those bags seem to make the ride even worse.

@DanH Thanks for taking the time to share your experience Dan! I really appreciate the details, especially with that many miles and a trailer of that size. It’s helpful to hear how well the Blue Ox has worked for you in real-world conditions. Your tip about using the jack to take the tension off the bars before engaging and disengaging is a great one. I’d just add a quick safety reminder for anyone reading along to be mindful when disengaging and make sure the bars are fully relaxed so they don’t spring back toward you. Wearing gloves and taking it slow there definitely helps. -Safe Travels =)

I have a 27' trailer that I pull with a 2025 GMC 3500 long bed (four door). The Blue Ox has worked really well for me. The biggest thing that I had to do was switch to the bolt-on mount because the trailer tongue is an open C-channel, it is not boxed. I also checked my tongue weight, but I used a different approach than Kate. At a Cat scale I weighed the truck front axle, rear axle, and both trailer axles with weight distribution engaged (so I had three weights). Then I weighed all three with the weight distribution disengaged. Finally, I weighed just the truck axles. This allowed me to see the tongue weight and how much weight I was shifting to the truck front axle. I the purchased a tongue weight scale from etrailer and checked the absolute tongue weight. This hitch is awesome. I have only had a bit of sway when hauling in 40-50 mph cross winds. I can easily back the trailer into any space without disengaging the weight distribution. And this hitch is quiet, presumably because the spring bar mounts on the hitch are lubricated with grease. No binding either.

@BobS Thanks for the response Bob, and the pointers how you weighed it at the CAT scale. I love hearing different ways to do things as there is usually not just one right way =)

Make sure when installing any type of sway control and pulling with a new truck from about 2020 and newer that you turn the sway control off in the truck. These new trucks will have built in sway control and it will make the sway control fight with each other and make it way worse.

My 32 foot (38 with the extended hitch) cargo car hauler was a nightmare to pull without any type of sway control. The blue ox hitch was the answer to absolute control while towing. I highly recommend it. 2022 Ford F250 SRW 4x4

@DavidD Thanks for the response David! Fun fact: every travel trailer has to get delivered to the Dealership, this is the weight distribution hitch that most of the drivers use, they use it for a reason because it works.
