Not much difference.
One rule to remember and print it into your brain!
Your pivot point are your rear tires on the rig. If they clear an object, you're good to turn
Turn before that and you're in a world of hurt!
With all due respect I'd like to clarify what you said to be sure others dont misinterpret it.
The PIVOT POINT is the HITCH point not the rear wheels of either the TV or the Trailer.
If you mean that if your REAR Wheels on the Tow Vehicle clears something then you are OK. I have to say this is not true in all cases it depends on how far rearward the trailer axles are from the hitch point.
My 31 footer TT tracks almost exactly on my rear wheel line of my TV. It is actually about 2" outside of that. On longer trailers that distance will increase. On *some* 5th wheels it may track on or over the line depending again on where the trailer axles are.
The easy way to test this and know for sure is take your rig to a flat dirt parking lot and make a continuous big turn (about 90 deg) and then go back and measure the two different tire tracks.
If you mean that the pivot point is the TRAILER axles, well it is true you will clear but you may not have this much room to make every turn and you should really know where your trailer tracks.
