So pulling with the HEMI was a breeze, no struggling at all. There was some sag on the rear end. The dealer suggested getting AIR Bags for the suspension to help with the load on the rear end. It was very windy yesterday, and it did not have a sway bar on it. So I can not give a full report on the handling of it. On the back roads the trailer was fine, stopping, accelerating and turning.
Not sure of the cost of the air bags, still waiting for dealers to get back to me on this.
