From the "almost exact" measurements photo, the center of
the wheelwell is 62.5 inches from the front of the camper.
It's probably not a good idea to mount the camper flush with
the truck cab, so add a couple of inches of space between them.
That puts the center of the wheelwell at about 65 inches from the
back of the cab.
