Trailer bounce

Yeah when I bought my truck I had to flip the shank and move the head down some. I mainly had the dealer do a double check. It had been riding fine until the last time I took it back to them and a tech moved the brackets for the torsion bars. I was not sure if that was affecting my porpoising or not. Regardless I do need to check it

I did end up downloading the manual and reviewed it so I will now what to do when I can get the trailer level. I also wanted it electronically so I can keep it on my iPad for future reference.

I had porpoising issues. I added SumoSpring Solo (similar to Timbrens) to alleviate that. Cheap and easy fix.

Check your weights and hitch setup loaded. I try to return my steer axle to 100% for best results.

As others have said, sometimes there’s just a section of road that sucks. My old fiver was a bear through Seattle on I5. The expansion joints matched up with my wheelbase so wrong my rig would start bucking like a bronco.

Sorry this took so long but waited for our first big trip. Here is my setup.

Front GAWR: 5200 lbs
Rear GAWR: 6340 lbs
GVWR: 10,000 lbs
GCWR: 22,500 (according to the Ford 2017 tow guide

Weights:
Steer axle: 4920 lbs
Drive axle: 5100 lbs
Trailer axle: 6160 lbs
Gross weight: 16180 lbs

In case my sig does not show it, I have a 2017 F250 SRW 4x4 with an 6.75 ft bed and a Diesel engine.

I have not had porpoising on this trip. The roads were better and I changed my load out slightly.
