Really not the best solution! Usually the issue with less than a smooth ride is something wrong with the set up of the TV or 5er. The Air pin box will reduce the shock you feel in the TV, but the 5er is still bouncing around.

Mentioned before Bilstein's on the TV, and bags if you need to overcome squat.

Then look at the 5er.
#1. Pin weight, while as low as 15 percent is stated to be OK, you will find 20 percent and greater will smooth the ride well. If FW tank is forward of the axle, run with it full.

#2. Is the 5er level when towing? The closer to level the better. Many was to get there 6" of rail clearance is enough, then still way off flip axles, or add sub-frame.

#3. install shocks on the 5er, this will reduce the multi cycle bounce and smooth the ride.

Now if you still feel you want a smother ride get an air pin box, or Mor-ride pin box,

One should not need an Air Pin box on a 28' 5er.

Agree 100%
Quality shocks added to truck.
Set up trailer to ride frame level.
Add shocks or equalizer cushions to trailer -I added Monroe gas trailer
shocks.
Make sure pin is at least 20% of loaded trailer weight.
Yes it can be a lot of effort to resolve the above things but the value achieved is the best trailer ride possible without a bandaid. A cushioned pin box will help ride quality but don't nust blindly add one as many time they actually complicate getting the trailer setup in a frame level stance.
