Correct. But, if you look at what you could either place some of that stuff in the truck, instead of the trailer (tool bags, for example) or, say, place the spare tire in front of the Jeep to balance the weight in the back.
I think this setup only makes sense if you have a rig under 4000lbs loaded, though, and closer to 3 than 4. Geos, light CJs, buggies, that kind of thing. For those cases, saving 800-1000lbs makes a bigger difference, than when you've got something thats 5500lbs + 2000lb trailer.
