Frank -
It actually makes sense now that I have spent some time with this.
Below are 4 pictures - all of the passenger side rear tire.
Notice that the truck unloaded has a smaller gap behind the tire (picture #1) as opposed to the front of the tire (picture #2).
So having 2 wedges (1/2") behind the tire (picture #3) and 3 wedges (3/4") in front of the tire (picture #4) seems more natural for our TV/TT combo.
