Is Friction Sway Enough

OP, I can't see needing wd or sway for that small of a trailer regardless of which vehicle it's behind unless maybe the trailer is loaded wrong enough to reduce tongue weight to an unsafe amount.
If that's the trailer you want, buy it, try it, get a wdh if you feel it's necessary after towing it around a bit.

I recommend the sway control for those unplanned wind gusts. They can hit you fast and hard and you very possibly may not have time to react properly. The little fifty dollar or so bar can make a lot of difference.

Barney, you are 100 percent right. Towing the larger camper for longer periods even with the ProPride can be a bit tiring. My wife and I both are very comfortable towing the 26 foot camper but for a 5-6 week trip across country 8-9 hour days back to back that can be tiring.
Also the smaller camper will be much easier if we get into a tight spot somewhere. Bottom line is IF we decide to get this TT, are we going to need a sway or WD. If we decide to do this, I will go to the local CAT scale to see where we are. At this point i'm just looking for some advice on sway based on using the Expedition. We use the Explorer to pull are boat which is longer and heavier than TT with no sway issues what so ever to make somewhat of a comparision.

Thanks

You'll definitely want a WDH if you tow with the Explorer, so why not just use it on the Expedition as well? For a TT that size, I would think just about any WDH would be fine, so no need to spend a bunch on a higher end one.

We towed an Apex Nano 193BHS with a Lincoln Navigator and while it technically didn't require a WDH, it definitely towed better with one.

Also, that 360 lbs is dry weight. Add propane, battery and gear and you'll probably be closer to 500 lbs.

You shd be ok with both. I think you mean 350 lbs on tongue weight or there about. Get a ball hitch with the small sway ball tab on the side. You won't need the big heavy adjustable head with sway bar seats. We have pulled 19 ft Airstream all over US with Toyota 4 Runner and Toyota Tacoma neither of which had WD. If you want to use two friction bars you will need to get a welder to weld the second tab on the draw bar.

Lwiddis,
Probably because the larger trailer may be on the edge of the tow vehicles capacity and makes the tow uncomfortable - especially if you are towing for a long day. A smaller trailer will be much more manageable for his tow vehicle and therefor less tiring. That would be my guess.

Why is everything ok for five hour local towing but not for eight or nine hour towing? NO magic in five hours or less but lots of wishful thinking.

I think this is a case of a physical test is needed. I'd expect not needing a WDH at all with the Expedition. With the Explorer, without a WDH, it's doable but likely an uncomfortable tow.
Your posted weight specs are confusing.
I had a 1998 Expedition with tow package, 5.4L and routinely towed a 10x6x6 cargo trailer loaded with about 3-3.5K# of band gear (with more in the TV). Hardly knew it was there going forward, stopping without trailer brakes was another story ;(
Bought current TT with a 2008 Explorer with tow package V6. GTWR 3877#. Was going to try w/o WDH going home, dealer talked me into a good priced used WDH that they set up perfectly. Glad I did, towed great but just moving the TT around the yard on a basic ball mount dropped the Explorer rear significantly.
Towing that same TT with 2019 F150 tow package V8, still using that WDH. But I screwed up and lost a WDH spring bar on a 60-70 mile tow so I towed it home with a basic ball mount. Only difference was a little TV rear drop and I felt the Lake Erie winds more so I drove home trying to keep at 60-62mph vice my usual 65mph & faster downhill.

I'd hook up and see how much it drops. 36lb tongue weight and it will sway. Need at least 10% which is 240lb. Unless that is a typo. At 361lb you will be close to needing a WDH, as the weight Carrying max for a Expe is 500lbs. and by the time it is loaded. you will be closer than you think.


Any thing else you use to level it, will NOT return lost weight to the front / steering axles. and that could cause sway as well. You may get a lighter WDH.

The only answer anyone can honestly give is "it depends."

How do you plan to load the trailer, and the truck? What's the actual loaded trailer weight, what's the tongue weight? How fast do you drive, do you like to bob and weave through traffic? Etc...

I used a friction sway when I was towing my trailer with a small station wagon. The trailer and the car weighed about the same, so I wanted a little extra control it provided. I haven't used it since upgrading to a pickup truck.
