Assume this on the F53 chassis. Looks under the Chassis forum for handling fixes, of something like that.
Suggestions to consider, not complete list:
> Four corner weight, and tires pressure set to manufactures PSI + say 5psi more.
> Safety T Plus - I consider this a safety item to help maintain control from a tire blow out. I also helps in shifting/changing winds.
>Calling Henderson Line Up, they can help you thru adding the proper Super Steer Rear Trac Bar, which will help keep the rear tail hang of the coach from pushing the front end around from winds. And they can also help you review how your F53 was ordered by your coach maker. (Different manufactures spec lower costing F53 chassis as far as suspension, to hit a price point. Believe Hurricane probably came in at the entry level price point, so probably not as many of the Ford available handling products for the F53. For example you mentioned Sway Bars, they may have only added one, vs in some chassis they have two on the rear end.)
Other things can be added during normal maintenance from wear. Like urethane bushings. Possibly better shocks (Not sure which shock, and what quality it was, from the factory on your coach. Could be Bilstien, and depending upon the year and the model, that could be a fine shock, or not their latest and greatest shock.
I'll also share that on our 99 F53 18K Chassis, besides I feeling the Safety T Plus was a mandatory add on for safety from tire blow out, the least expensive change I made to the coach - were Air Tabs. It as the last thing I added, from additional sway bars, rear track bars, urethane, and a few other mods too. The rear Tail Hang on our coach was enough to really let the wind push/leverage the front end from side to side due to shifting cross winds. Adding the Air Tabs really cut down on the impact of:
-The Bow Wave push as a semi came up from behind
-The Sucking You Back In as the semi finished passing you
-The impact of shifting winds. Like when you go under an underpass and get the momentary block from the wind, but then clear the underpass and the wind hits you again.
-And the rear camera stayed dryer in rain, and the toad was cleaner too.
Some report MPG improvement from Air Tabs. I probably picked up 1/4 MPG, or a bit more, over about 15K's of usage, compared to the previous 15K or so of history. But MPG was not my main reason for adding Air Tabs, it was for the help in the shifting winds. The least expensive mod I made to help handling, and of course, the last one too
Do changes in increments, and stop when you feel you have the ride you want.
Best of luck to you,
