It is quite possible to load the trailer so the Trail Air air bag is maxed out and quits working, and the air bag only cushions up and down movement. The Mor-Ryde has lateral movement that cushions the "chucking" or jerky fore-aft movement towing on a not smooth road. It also allows missing the perfect alignment when hooking up as it will give a bit side to side without forcing the trailer to slide on the landing gear.
There are pin boxes that claim to dampen both lateral and vertical movement. We found we were only concerned with the lateral, and the Mor-Ryde works.
Also, consider the tires. You will have 12,000lbs on them, so you want a tire rated at 4,000lbs or more so that you are only loading them to around 80% or less.
