I do believe I saw somewhere where a member did just that not very long ago. Have you tried to search for it? I know the search function doesnít always give you great results but you never know. Good luck.
The dealer added one to my '12 JKU. I'm pretty sure it's not plug-and-play as I understand it. They ran wiring up to the battery and tapped through the firewall to wire in the brake controller. It's a nice installation but not like on some vehicles where the wiring is already there for the 7-pin and brake controller.
What type of popup do you have? I just got back from a 1500+ mile trip out to Big Bend National Park pulling a Coleman E1.
The Jeep does fine on the flat sections but when things started getting steep I had to fight to maintain speed. Mine has 4.10s and a manual. My trailer is pretty tall which doesn't help and it's probably pushing 3000# loaded.
My biggest complaint was the mileage I got. Overall, the on-road mileage was between 13 and 14 mpg.
I had one put on my 2007. It's a Mopar one, not exactly plug and play but not to bad. I try to stay as close to 3500lbs as possible but with the weight of people, dogs and mods I'm always a bit over GCVW. With a head wind the Jeep struggles. I'm on 37s with 5:13s and Hypertech and it just needs more power. We don't go far with it but we wheel the Jeep when we get there. Sometime this summer I'll hook it up to my wifes GC Overland, I know it'll pull it easier. The 49 sq/ft front on the trailer doesn't help. I had a hole cut in my Teraflex rear bumper for the plug.
Not sure why you don't like it, it is an awesome place for the wiring. Its tucked up in there, no issues with trails. You can change the bumper etc and no worries and it works great to keep the wire up and away from carnage with the offroad trailer. I have a modified M100 trailer I use with this and it works perfect and looks OEM. Trust me, this is the way to go.
