mike , just mounted blue ox base plates on my '11 wrangler. they roughly finish off with the bottom of the mount close to level with the bottom of the bumper, and in my case no change nessary to hook to coach.
i NEARLY went with the cool tech wiring harnass, until i found out i had to cut into the jeep wiring anyway (if i had factory tow package), so i went with the seperate bulbs myself (from blue ox).
oh, and you MAY have to disable the jeep brake lights. if your add on brake presses the pedal (and light the brake lights). what that will do is HIDE your turn signal of the add on lights, activated from the coach. my book says to pull the neg post (to accomplish this), but at least you may have to pull that fuse ( brake light).
I'm not DONE with mine yet, so feel free to PM me through this process.
