What were you expecting from the CHF? It does nothing else than making the sway bar "stiffer" (almost acts like a beefier sway bar). That means, it reduced the lean in cornering and partly the push from passing semis.
A steering stabilizer will not do anything magical either, it helps to keep the steering in a more center position. Some of that can be achieved with a front end alignment and more caster at the front end.
If you want help with the cross winds and more help with the passing semis, you should consider a track bar in the rear, and maybe in the front, too! And the next step would be the installation of either Sumo Maxim springs or air bags.
I have all that installed and am now at a point that I sometimes only realize that a semi is passing me once I see it next to me. Cross winds don' t bother that much either anymore. The days of "white knuckle" driving are over for me.
But I am still driving a truck, and the harshness of the ride over bad roads is still there. I am working on that currently. My final goal is to get a ride quality that is similar to the one that can be had with air springs (without paying the high cost for a Kelderman system which has achieved this ride quality).
