With the camper:
First impression: Wish I could remove them right away, the ride is miserable.
After a while: The pendulum-like swaying did disappear, but the truck effectively has almost no rear suspension. It's like (it is?) riding on the bump stops. This is not the long term fix for us.
Without the camper: everything is okay most of the time, but any decent amount of bump (i.e. going over most bridges) was bad. The rear suspension would compress enough to engage them, and the effect is (unsurprisingly) jarring.
Same problems we had with the older '60 to '72 half 1500/2500 pickups with the trailing arm rear coil option.
Plenty of spring also and sure didn't need any more spring assist but body roll was downright dangerous. The only way to stop it was get on the brakes. The only fix was the heaviest sway bar available on the front and rear and a twin shock setup at the rear corners.
The coil setup on the Ram is light years ahead of those old trailing arm setups.
If you go with a heavy sway bar I would go the the rear first, then the front if needed.
