This thing is a beast. I bought mine to go on my 2014 Jeep Wrangler Unlimited. I have a lot of custom mods, including a custom fabricated stubby bumper. After trying to mount it with some help from a tech that belongs to my Jeep club we realized we would need some specialized help mounting this.
I would say that mounting it on top of a bumper would require little effort, however if you're mounting in a recessed location inside a stubby bumper there are some logistical issues that can require some additional modifications.
First, the vacuum pump will need to be relocated to the engine bay to accommodate the winch. Even with this relocation, you will likely need to trim a little metal from the bumper mounting brackets. Lastly, depending on the depth of the winch mounting plate, you may need to fabricate a custom extension in order to orient the winch properly.
That said, now that all the mods have been done, this winch is awesome. The reason I bought it was after my rugged ridge 8,000 lbs winch failed me in the trail. Most winches have a port on the winch to connect a wired remote for operation. Problem was the plug that seals the port came loose while I was getting stuck in a 4ft deep mud pit. The inside of the port became filled with mud and despite trying to clear it of debris, I wasn't able to get the remote to connect to operate the rugged ridge winch.
