Propoising - Timbrens or Airbags?
I have a 2016 F150 2.7 crew with payload pckg w/payload of 1718 and tow a 30' TT that says about 7000 pounds loaded for a trip. I'm using an equalizer WDH with 1200 pound bars. Overall the setup tows nicely and the truck sits level with the trailer so I don't need them to help with sag.
My biggest complaint is the bouncing of the rear end when going over bumps, which I've heard of as propoisong.
Which is better to help with this concern?

While not exactly the same, I added the Road Master Active springs to mine to help with an 8k enclosed and loaded car trailer. Coupled with the Fox 2.0 shocks, the rear of my truck is a decent amount better, although still too soft.

I don't understand who you are propoising to?
Porpoising is what you are referring to, more commonly used when describing boat actions.

Neither one will do much to control porpoising/undulation. It sounds like you just need a set of premium shocks. I'd look at Bilstein or KYB.

I have Timbrens. Being s large piece of rubber should help it out. Plus, they only cost $210 and takes 30 minutes to put on. Shocks just dampen the rebound, stiffen up the rear and it should be fine.

I'm thinking stiffer shockers and maybe LT tires for a stiffer sidewall.

The fix is simple.
This is usually caused by your WDH bars not being set tight enough. Go up a link or two on the chains and you will eliminate the problem.
Basically the front end of your truck is unweighted too much.
This is a simple no cost fix. Just try out what I suggest and go for a drive. I have seen this happen with people more time then I can count and the overwhelming majority of the time more weight on the bars fixes it.

The front of your truck is unweighted from the leverage of the trailer tongue weight. This is what starts the bounce.
Give it a try and see if it works.
