You can order the baseplate from Roadmaster. I've had no issues with mine at all. I'm using the All Terrain Tow Bar that works just fine----6000lb capacity. In fact it tows just as well as the 3100lb Subaru that I had before.
I'm also using the Unified Brake system from US Gear. I've towed my Jeep over 2500 miles so far and I'm very satisified with it.
By the way, Roadmaster also makes a nice, hard cover for the brackets on the front of the Jeep so you won't have to bother removing them-----if you don't want to.
If you want more info, send me a msg
