Interesting. I've never put more than ~35psi in them and that alone made the truck rear go up a couple inches. Nearly triple that sounds crazy! I'll give that a go before removing them to see if it changes anything. Thanks!

I went from P-metric tires to LT tires and found a significant reduction in bounce. Same truck, same trailer, same roads. Less sidewall flex.

Wow, I was wondering what was causing my truck to bounce a little.

Thanksgiving morning, my brother-in-law's 75 Maverick broke down 10 miles from his parents' home, and I offered to come get him. Hooked up my FIL's car hauler to my truck and walked it up and out of his front yard (yay, 4WD LO), and went and got him.

On the 10 mile trip back (in NW PA), the truck was a little bouncy. I thought it was too MUCH tongue weight.

Here's what it looked like:

I would say that the boat is sitting too far back on the trailer, not giving you enough tongue weight. As posted earlier if you can move the winch forward it should help.

I've always towed trailers for recreation and for my business.
1994, 2004, 2010,2015 F150's to name a few , after I got the 2015, where the truck is lighter in weight. I think some of the trailer movement/road vibration is transferred to the truck. The first trailer I hauled with my 2015. A trailer I had used 100 times with my 2010 F150. I felt vibration and trailer movement in the truck and steering wheel. Is it the aluminum body transferring the vibrations ? Or just the overall truck being lighter ?
I delivered to Vermont yesterday towing a 5' x 8' enclosed trailer with 500 lbs in the truck bed and the trailer had 1000 lbs in it . My mileage was 16-17 mpg. I'm thinking the vibration transfer is less with the trailer loaded. But empty its really noticeable.

The few times I've towed, I always noticed it in my father-in-laws trailers ... a little bounce or sway, but not more than a few inches in either direction. Definitely towed smoother once the trailer is loaded. And that's on my 2011.

I have a 2015 Lariat and have only towed my 25' 3 float pontoon 1 time with my F-150 but also had the annoying bouncing in the rear end. I also have an 05 Expedition that seems to ride better while towing. The F-150 pulls and stops much better than the Expedition I just wish it didn't bounce so much. My Pontoon and trailer weigh no more than 4000 lbs and tongue weight is around 400 lbs.

Very interesting topic, I figured I would chime in!

Several factors would obviously come in to play when it comes to bounce. Def agree with some of you guys that the tires, vehicle weight, WDH, the trailer itself as some have suggested will all come in to play.

The loaded trailer, hooked into a lighter weight truck with softer leaf springs not quite equipped or stout enough to handle the weight (vs years previous). The additional weight will dissipate down through the leaf springs to the tires cause that continuous up and down tire sidewall and leaf spring flexion. Almost a form of a "tail wagging the dog" scenario.

We deal with these types of bounce issues on lighter duty trucks nearly every day, absolutely perfect application for the RAS. RAS is unique in the way it keeps the leaf springs strong/stable at all times and becomes progressively active. If you haven't heard of it check it out over under the vendor portion of the forum, check out reviews on the forum, or ask me any questions straight up.

Thanks Nolan, I will look into RAS. Going to check trailer too. It is a 25 foot pontoon on a 24 trailer.

I just ordered a set of the RoadMaster active suspension coil springs....it looks like very easy install for a non-gearhead like myself. I'll let everyone know how they work when loaded or towing. I'm still very skeptical...but will give it a try.
