Smile Shock absorber replacement

Not sure if this should be here or under mods.

We have a Sunseeker, on an F450 chassis and it had about 69K miles on the OEM factory original shocks.

I replaced them this summer with 4 Bilstein shocks specified for this chassis in a motorhome application.

It was not inexpensive, but after 4000 miles from NH to Illinois to Texas to Ca, I'd say it was definitely worth it.

Smoother ride for sure. Those tooth rattling impacts whenever the tires went over concrete expansion joints on cement roads and smaller road pot holes were essentially gone. Sure, there were a few, but I think those were the bigger bumps/holes than the previously felt "almost every imperfection" that we endured. Part of the issue, I am sure, is the high inflation pressures (65 F, 80 R) that I run tires at because we are so near max load rating.

Anyhow, the 4 K mile trip home was a much smoother ride, potentially less sensitive to body roll and buffeting but that could be my wishfull thinking. (Biggest improvement in that was replacing the factory rear anti sway bar with an aftermarket one from Camping World. Went from factory original of maybe 3/4" dia to about 1 1/4 or 1/12 (?) diameter. BIG improvement.)

By the way, I try to have any expensive scheduled or elective work done in NH because there is NO STATE SALES TAX! That saves a few bucks every time!

Harve I'm about to do something similar, I have a 2012 Sunseeker with 57k on an E-450 chassis. I was thinking about replacing all 4 shocks because of the body roll and sway at highway speeds. I've got my airbags at 60psi and my tire pressures at 70f/80r. My question is; the part numbers for shocks change between 2011 and 2012, my Sunseeker being a 2012 is technically riding on a 2011 chassis, so do you guys usually order parts for the year of the chassis or the whole unit? I suppose I could bring both home and take back what doesn't work but I thought I'd ask you guys first.
