I had the same need, and did a bit of research and settled on Downey coil overs (600 lb) and a 1 5/8" lift rear shackle from NWOR. I don't want much lift myself, just about 1.5 inches after installation of ARB and winch, and a suspension to handle that load for moderate (nothing extreme like rock crawling or desert running at high speed) off roading in a camping / hunting truck that sees some hard use.
The OME's I understand will sag, and are rated at 500 lbs across the board for all their coils 881, 882, etc (stock Taco coils at 420 lbs I believe). They simply stretch out the same coil to get the additional lift. They will eventually sag and fail with the added weight of an ARB and winch (or so I'm told).
I stayed away from other coil overs because I want the option to purchase shocks instead of rebuild (even though the downeys are rebuildable), and some of the coil overs will leak over time and require recharging at a motorcycle shop (more hassle). (I understand the Donahoes don't have this problem, but too pricey for my taste, and again, need rebuilding versus buying a new shock).
I also went with coil overs versus any spring set ups because it allows for easy shock replacement in the front now. No worry about spring compressors or taking it to a shop to have it done at increased cost.
Coil overs have the additional nice feature of adjustable lift. Add a winch and bumper later, crank it up. Take winch and bumper off, crank it back down. Driver's side spring sag, crank up that side a bit and level it off. You don't have to worry about shims and all the trouble it takes to install those after things settle.
I was told to not go much over 1.5" on the Downeys (with a winch and ARB) otherwise you could get some coil slap. Not a problem for me because I didn't want much lift.
I got the Downeys for about $710 shipped (I had to pay tax as I live in Kalifornistan where Downy is), and rear shocks and shackles for another $200, which puts me at about $910 for a winch and bumper capable front suspension and lift in the rear to match.
I cannot yet attest to this set up, it is going on with the winch and bumper this weekend, and will see some off road use soon after, but if you're going to be a while before you buy I can give you at least a first impression in a few weeks.
