Need Input on Ride Quality - LTD vs. Trail

[LandCruiser]

On similar tires an XREAS LE rides similar to a TE, but the interior is nicer, so it's comfier. The 20" bicycle tires actually make the LE ride harsher than a TE with much thicker sidewalls.

The SR5 wallows since it has neither suspension system.

Could one add the Trail sway bar to the Limited which has full time 4wd?
