Shock absorber question

Just brought the coach back from her spring check-up. Brought her to a highly recommended facility with lots of trucks, buses, RV's in their lot. I gave them a list of standard items to check, including shocks. Our ACE 30.2 is a 2015 on a 2014 chassis. She now has 32,000 miles, having driven all over the US. Good roads, bad roads (lots of bad roads), mountains, more mountains, and flat lands. She has safe t plus, sumos (front and back) rear track bar, CHF, 4 corner weights, and properly inflated tires (per Toyo chart). Over the last 2 years the ride has felt bumpier--like the rear is bouncing down the road. For two years the truck guys have told me the shocks are fine when I say that I think she needs new shocks. Finally I asked why they felt the shocks were fine, and, drum roll please, it is because they are not leaking (insert eyeroll here). So I got an install price and the service manager said to get the shocks I wanted. He suggested Monroes, and said he has a hard time getting Bilstein's or Koni's. So, am I off base in feeling that I need to replace my shocks? I have always used Bilsteins as my go to replacement shock. They really reduced the bounces over expansion joints and crummy roads for my prior coaches. Is this still true? My current gasser is slightly bigger (longer back overhang) and heavier than my prior gassers.
Thanks for your suggestions.

You have 6 years of usage and 32000 miles on the shocks. As you have invested in all suspension upgrades to improve the handling so why wouldn't you upgrade the shocks at this point. IMHO if Bilsteins have served you well in the past then that would be my choice.
I used to think Monroes were good shocks but not these days. I just had all 4 shocks replaced on my 2010 Ford Ranger with Monroes little less than 2 years. The little truck has 78,000 miles on it and the OEM shocks lasted 9 years and 75000 miles. The "new" Monroe shocks on the front are rattling and leaking fluid already.

What is CHF?

Lots of talk about CHF - what is this/these?

It is the "Cheap Handling Fix" to stiffen up the sway bars by moving the links to the inner holes on the bar. It costs nothing but a little elbow grease to improve the handling on most F53 Class A Ford chassis. Doesn't apply to the Ford 350 and 450 that Class C's are built on.

Thanks

Got it - since I have a 350, will focus on the other recommendations for improving handling and steering!
