Actually did this several months ago but haven't taken time to post- installed a Smittybuilt winch: waterproof X20, 12000lb, synthetic rope, with wireless remote, was $570 on Amazon at the time.
Installation was a bit of a trick, so wanted to share some photos. I know the Dissent bumper is supposed to be able to fit this winch and controls, but I wasn't happy with how buried everything was if it all went inside, and it was almost impossible to ever plug in the cable (in case the wireless didn't work). I also wasn't sure how well the wireless feature would work when surrounded by that thick bumper metal, and really liked the idea of being able to walk around out of harm's way as I winched, so thought outside was best:
Thankfully
@benc 's bumper design means you can work on the center section by itself (lighter and easier!). I took apart the control box, used its bottom plate for my template:
then ran the wires through the bumper, connected them, and mounted the guts:
Here's another view. You can see what I mean about mounting the control box inside- it's TIGHT with this winch already, and that big cable does not like to bend easily. Not sure how others have done it...
Overall I'm super happy- easy to reach the on/off switch, wireless works a treat, and if I ever need to plug in the cable it'll be easy. Great winch too, used it half dozen times on a brutal snow run and was a champ - 10/10 would recommend.
