I was gonna say that it would be overloaded if you tried to hook your trailer and Jeep to it, but down in the "Q&A" section of the ad, he says it only weighs 8100. I wonder how much it is with people and gear? My CTD K30 crew cab weighs about 7500 with 2 people, dog, tools, and misc. When I picked up the slide-in camper the other day (still had 2 people, dog, and some tools), it weighed 9300, and only had 4700 on the rear axle.
So as long as the rear axle weight and tire ratings are within spec on this rig, I guess it could pull a trailer and trail rig. The main thing to watch for would be how far the rear overhang sticks past the rear axle to see how the receiver hitch and tongue weight would work.
