I have a 2019 2WD F150 V8 supercab which has 2320lb payload capacity.
I have a FWC Hawk installed.

I have e rates tires and have installed Timbrens and recently bilstein 5100.

The ride remains a little harsh and bouncy. I’m wondering if that’s as good as it gets or since the camper is a permanent install in the truck, I should explore something else?

- helper springs (hellwig?)
- torqlift stable loads
- sumo springs
- something else?

I don’t wish to spend a ton of money and I’m also out off airbags due to the need to adjust pressure and less reliable / more maintenance than rubber or metal springs.

What do folks recommend for a more comfortable ride? We drive mostly highway with the occasional potholed gravel road.

I had Alcan Spring Co in Grand Junction CO, build a custom spring pack for my F 150 Fx4 with a Hawk permanently mounted. I requested 1100 lbs additional capacity with OEM height. The ride is perfect on highways, two lanes and off-road. No harsh ride, no bouncy. Of course if I even took the camper off, I suspect I'd bounce all over the road, but I don't plan to take it off. I did the same on my previous Ford Ranger FWC Eagle combo.

 

 

They will make a custom spring pack to fit your specs. Took about 5 weeks and then I made a trip there, picked them up at there factory and had them installed at Top Notch Garage about a mile down the road. Alcan will also ship them to you.

What tire pressures are you running and what does the placard on your door jamb say?

The very best way to obtain a decent combination of ride and handling with a permanently mounted camper is with a set of custom springs tuned to the weight, as Larry did. Invest once and forget it. Timbrens and Sumo Springs are really just glorified bump stops and won't help your ride. You might be able to get away with an added leaf, but if they're poorly designed they can add stress risers to the existing pack.

Here's what I posted in another thread some years ago, and I'm still happy with the Roadmaster coil springs.  They are adjustable.  Assume they are still available, and were reasonably priced.  Also recently upgraded my rear shocks and ride is very good on paved road and off.   In the meantime have upgraded to E tires (from P) and that makes a big difference too.

 

Unlike air bags or extra leafs, they won't break or fail and operate only when loaded, and no maintenance required. I recently did a 2-week trip in my 09 Silverado 1500 with a camper at payload capacity, and it handled very well on all types of roads from highway to 4x, in wind and curves, and steering is fine. When truck is unloaded the extra springs are inactive.
