My 2 Cents
Last winter, before our annual New Year's trip to Houston, I finally had the CHF done on our 2013 A.C.E. 29.2 which we've owned for 4 years. As others have remarked, "Wow, what a difference!" I began with an alignment in 2014, then added a Safe-T-Plus, each of which made a cumulative improvement in handling. But the CHF improvement was noticeable pulling out of our service tech's driveway. The usual swaying side to side was almost gone. Since then, we made a 2,500 mile trek through the west with no issues with passing truck and buses. Pay attention to tire pressure too. It helps loads!
