The main rationale is there are a lot of vehicles produced that have the power to tow loads that are pretty high, but when you put the tongue/pin weight on the TV you run out of GVWR.
Case in point, my truck as a GVWR of 10,000lbs, but a GCWR of 25,000lbs. Unloaded the truck weighs about 7.500lbs which means I could technically pull a trailer weighing 17,500lbs. If you go by the standard 25% pin weight on a 5th wheel, that would be a little over 4,300 lbs on the bed of the truck.....which I don't have capacity to hold. So, if I were to use a dolly system, I could have the bigger 5th wheel, stay in the weight ratings of my truck, and have the bed free and clear for bikes, gear, etc.
I'm not sure I would like using the system, but it seems like a decent option depending on your needs.
