I ordered from Lippert and had my mobile RV tech installed it. I already had a Trail Air king pin hitch, but the Center Point really smoothed out the ride. Nothing moves in transit. Before the air bags stuff walked around. It claims to eliminate 95% of the road shock transmitted from the road into the coach. Based on what I've seen its believable.
If it spares one piece if electronics or keeps the structure a bit sounder then its worth the expense if you plan on keeping the trailer. If you trade often you might save your money.
