MetalGator,
As has been stated, the distance from the point of attachment on the motorhome to the point of the attachment on EITHER JK, is the EXACT SAME. Your 4 door could be stretched to 3 times its length and, it will still have the same distance between the coach and the front bumper/base plate attachment. There is no difference between the two Jeeps and the coach.

P.S. I just read your third post again. If you take a birds eye view of this situation, you'd see the tow bar makes a triangle between the motorhome and the Jeep, either Jeep. Unless YOU CHANGED one of the bumpers on one of the Jeeps, or, the tow bar attachment points on the JKU are different the the ones on the JK, the distance between the two vehicles IS THE EXACT SAME. If the two Jeep Jeeps have the exact same setup, i.e. base plates and, the bumpers ARE THE EXACT SAME, then the tow setup, IS THE EXACT SAME.
When turning, still looking at this in a birds eye view, and you turn your coach at a given angle, the responding angle between the coach and the Jeep, WILL BE THE SAME, no matter what jeep you're towing. The only difference that may have to be taken into account is the TRAILING length of the vehicle being towed.
Obviously, if you're trailering a really, really long toad, say a 4-door long bed pickup, then the trailering effect of the length of that truck, i.e. the term "cheating" comes into play here, the truck will CHEAT on the corner or, it will take a shorter path/arc in the turn.
But, the distance between the corner of the coach, and the front bumper of the truck is THE EXACT SAME AS TOWING YOUR 2 DOOR JEEP. I know, because we tow either a 4 door JKUR or, an Extended cab GMC Sierra 1500 4x4 truck.
