I don't see a response on which suspension/GVW/Trailer weights packages you have, but speaking from experience from two different Super-Duty pickups, with both I added Air Lift air bags to the rear. Both times it turned our really well. You can adjust the pressure to avoid issues like you have described as well as changes in loads, different trailers, pavement irregularities and etc. If you have the on-board compressor, which I highly recommend, you don't have to stop to make changes. The new WirelessOne system uses a handheld remote to make adjustments so you can even make adjustments while outside the vehicle and use different pre-set pressures for you trailer.
