I had the 884s on my A-cab. No top plate. Without the winch and bumper, I still couldn't get it aligned right (though it rode fine enough, but I just ordered UCAs for my 886 set up). With the winch and bumper it road like a land yacht, dipping, swaying, rolling every which way. With the 886s, no top plate, arb, winch, and no sway bar it rides great, minimal body roll and the front actually isn't too bumpy, the dakars are pretty stiff out back though.
If I HAD to pick a coil for your set up I would go with 885s, but I'm not too sure.
My alignment specs with 884s (no winch/bumper)
I guess I should add: I liked how the 884s rode and handled with stock UCAs and no bumper. I hated how the 884s rode with the bumper winch and stock UCAs but liked how it handled.
I like how the 886s ride with the bumper and winch, but I don't care for how it handles now (it wants to follow ruts and feels floaty, ALTHOUGH, this has only been since I moved up to 285s) , so I've got UCAs on the way.
