I just acquired and installed the Viper 13K and haven't trail tested yet. The assembly was super easy - it comes already wired so just mount controller, drop winch onto plate, and run supply and ground.
But 10k is NOT more than enough winch for a JK. As the winches rated capacity goes up - the amps drawn to pull actual vehicle weight goes down. With an 8K winching 4000 lbs will pull over 300 amps. With a 10K winching same 4000 lbs draws about 275 - with 13K it draws about 190. Thats load directly on the battery/alternator. More load will always equate to more total cost of operation as the cables etc will be effected and require repair more frequently. I did install an 8K first (budget dictated) and as such the cost of cabling to handle the high draw, the control solenoid (I refuse to maintain an unfused 0 guage hot lead on the impact zone of front bumper - thats just asking for a fire after a minor fender bender - so I use a 600 amp solenoid to control the winch main power) etc ended up costing the same as the 13K did. But now my wiring is so underloaded I should be worry free for the next five years!
And also to consider - that max weight rating is for ONE WRAP of the wire. Next wrap the rating goes down. So if you have a 100 foot wire on an 8000 lb winch - you only are at rate with two wraps on a 4250 lb vehicle. So to winch from 25 feet (Approx 4 wraps left on winch) - you are overloaded (and amp draw goes up accordingly) unless you pull all 100 feet off and use a snatch block - which halves the winch speed and requires extra effort then to respool (which should be done anyway - but at least when properly rated you can use multiple times in one day then respool at trail end maintenance rather than respool before every use)!
I recommend 10K for a two door and 12K or better for a four based on my understanding of the principals and experiences.

The wagon should, of course, be as light as possible, but strength should not be sacrificed to lightness, for on any but the regularly traveled roads, the wagon will get many a hard knock
