I have a 2014 F150 SuperCrew. 5.0. Eibach Leveling struts up front and I HAD Eibach shocks in the rear. I was experiencing what you are describing. The biggest thing I did to get rid of the bounce was to install a set of brand new OEM shocks on the back. The Eibach's were valved WAY WAY WAY to firm on the compression side. If I were to order up different shocks for the back it would be from Doetsch.

Do you guys have enough weight in back?

I was going to bring this up... I have this as well. But I also have 285s all terrains, 2.5 inch lift in front and 3inch block in the back. once all that was added is when I started feeling bumps real hard... But noticed if I had a couple hundred pounds in the bed it seemed to reduce the bounce/rough ride.
Was thinking of upgrading the shocks in the rear. Just wasn't sure which ones to go with.

I've got the same bounce/hop in my 2014 Lariat 2WD screw 3.5 eco... have had tires road force balanced twice, swapped wheels/tires with 2017 model and nothing changed. I have 15k miles on it (just bought it a month ago) so it's still under warranty until Feb 2018. Dealer has tried all of the above, but basically told me that's how those trucks ride. I asked him to change the rear shocks and he said no / I didn't argue because I don't want the same junk installed again if it's the problem. . He did say there was some Ford Thread on a forum for the F250 where they added weighted blocks to the rear to correct the bounce. Not sure where or how they mount, but he said I would have to pay for it.. I told him I'll figure it out myself. So... I've ordered a Ultra Flex tonneau cover (60lbs) and Fox 2.0 performance rear shocks. Hopefully I'll get them before the weekend when I do my monthly 1000 mile round trip to SC from GA for military. Once installed I'll let you know if it helps.
My bounce is felt all the time - from slow rolling to just over 60mph. And when I go over a speed bump it takes 4 bounces before the truck settles... bad thing is - I drove another 14 Lariat 2WD to test and it did it worse than mine, but had 60k miles. I'm hoping it's just the shocks are too wimpy

I have a 2012 screw with this same bed bounce on the highway. Seems to be only on concrete roads. In the 70 to 80 mph range. Bed bounces bad. The second the truck hits pavement, it stops. I have tried different tires, max air pressure, less air pressure, Bilstein shocks and no help. Just got new tires. Its now just a smoother bed bounce lol. Currently running Raptor Fox shocks. No help there either. A mechanic at the Ford dealer I go to has the same truck as me but a 2013 and he says his does not do this. Anyone have any more input on this?

Glad to hear I'm not the only one that wasted my time buying new shocks with little improvement lol At least I know they'll be good for a while, for what they're worth.
The truck rides pretty smooth on the highway but on city streets that are bumpy it can get pretty frustrating.

Did you ever try the weight in back, Sonic? Trucks are heavy, yet very little of it is near the rear axle. Gives a different feel in back than any other vehicle type. I have much less bounce with my cap on, that's ~180 lbs on top of whatever I'm carrying. I'm still on original shocks at 80k.
Concrete roads pose a different issue. Those tiny little spaces between concrete slabs can get a vehicle rocking at certain speeds and wheelbase lengths. This could possibly be what some are feeling. If it goes away by dropping or increasing speed just a couple mph, that may be the problem. And there is no solution except to avoid that exact speed range on that road. Very seldom affects cars with their shorter wheelbases.
