Yes, driving with Dark Aero attached is a much better experience!
I still have tuning to accomplish with the air shocks and load distribution. I think my truck tire pressures are at 30psi across the board and 60psi on Dark Aero. Stock pressure is listed as 26psi front and 29psi rear fer the truck. Air bag spring is at 30psi. Air shocks are at 100psi.
I haven't noticed any steering wheel inputs from Dark Aero except in strong cross winds. I haven't played with the current hitch setup enough to notice anything just yet. I can say that I'm not tired from driving the rig as one would expect towing a normal trailer setup. This setup rides really smooth!
I will have to try out differing tire pressures at some point and see how that fares out.
