I have a 2017 AF 990. (looks like I need to update my sig)
Had a 2017 F350 Ext cab, Ranchos, airbags, Stableload uppers.
Spent way too much time messing around with airbag settings. Never felt comfy. You can search my handle for some of the discussion.
Upgraded to a 2020 F350 Crew cab.
Put on the 18" Method NV wheels rated for 4500 (I believe) as well as the Toyo F rated 4000lb Tires.
To that I added the Stableload lowers and some other replacement upper stops that were cheaper than the SL uppers.
Did this after consultation with the folks on this forum.
Real test (the SO) passed immediately on first ride (and for me too).
My opinions:
Air bags suck for this setup. You're well overweight. (Cat scale for me for the weekend is around 12k). Hunting and pecking for the right air pressure drove me nuts.
Lower stable loads removed all of the sway. I've driven commercially for years in the past so I'm accepting of the changes 5k of weight (even AF states ~4800 loaded) in the bed makes and this setup is awesome.
My suggestion to anyone with a heavy camper for the truck and the truck is not a dually, install stainless steel lower stable loads as your first task. You need to engage the lowest spring in the pack (the stiffest one) early. You CAN drill the springs yourself but you have to be creative. Took me about 45min/hole including setup time and working solo.
The tire/wheel combo provides me the mental comfort that, although they're close to limits, are within limits. Can't say that I can feel a difference in the stiffer side-walls from the stock tire/rims, but it follows logic that there is.
I almost went the 19.5 route until folks here caught the fact we go on sand and saved me ton of aggravation.
One last addition I'm making is a rear shock change because I do go on sand and the stocks aren't up to the task. Now, Bilstein vs Rancho? I haven't had bad luck with the Ranchos in the past. I'll post update on that.
