Well,
My wife and I spent almost three hours this past Saturday with a tape measure and wrenches putting our new Dual Cam system on. We then had to move the ball up two holes which meant changing which way the receiver bar was postioned. Got a lot of practice backing up and hooking up. My TT is almost parallel front to back as measured from my driveway. My TV sits at the same height in the front but almost 1 inch lower in the rear. My Tahoe has such a soft rear suspension that the TT settles it down about 3 inches without the WD bars set and only 1 inch with. The math that has gone on in this discussion has been great but I'm sure the weight of the TT tongue that sits on the ball of my TV is actually less than before since I now have the TT riding parallel to the ground. With this move, the energy required to hook up the WD bars is less than before. In a few weeks the TT and TV will do a trial spin of a few miles to verify the cost of equipment and time spent.
