F-150 suspension upgrade for towing needed.
I have a 2015 F 150 with tow package.
We just bought a 26 foot travel trailer and discovered we hump bounce on some concrete highways. Is there anything we can do to stiffen suspension to stop the rough ride?

 

I have the same issue. I have 2015 F 150 FX4 and I am towing a 2016 28' Jayco weighing 6950LBS. I have a WDH that the dealer setup for me, but when I was pulling down the hwy it started to bounce really bad. I pulled over because I thought maybe of the stabilizer bars came off. When I went down the hwy with black top I didn't have any bounce. Not sure what is going on. Maybe the dealer didn't set up the WDH right.

 

Think I may consider adding air bags in rear suspension. Hate to have to spend $1,000 but better than porpoise bouncing.

 

Need to visit the Towing section of the forum and provide a lot more info.

Payload sticker?

Weight of all add ons, people, pets, other items in truck?

Tongue weight?

Trailer weight?

Weight distribution hitch with proper bars?
