I too did the CHF and it made a big difference. Just make sure you check your clearance with the leaf springs In front and the the bell housing for the rear diff. Mine cleared fine on our 2010 HR but not well on my father-in-laws 2006 Sea Breeze. When he lifted his wheels of the ground (with jacks) the sway bars touched the springs in front. The rear bar pivoted closer to the bell housing than he felt comfortable.
We just came back from a 3 week 5,000 mile vacation and all performed very well. I do recommend the CHF but just be sure you do not have a clearance issue.
