The counties did (and still do) number miles, but not exits.

The reason I want toll routes numbered differently is so that people
don't get surprised by the toll partway through a trip and have to waste
time going around as a result.

In a case like that, the non-toll number would be moved to a contiguous,
non-toll route (not necessarily all freeway) wherever possible. I can't
think of any case where this would require new construction, though it
would mean some existing numbers get moved. (For instance, I-80 would
move to follow the present I-74/I-71 route between Rock Island, IA/IL and
the I-76/80 junction in western PA -- a routing that truck drivers
already regard as the "standard" route because it avoids all tolls.)
Similarly, I-70 would follow I-68 to avoid the PA Turnpike, and I-95
could follow I-83/81/84, bypassing New York City (though I-95 is diagonal
and so would be renumbered or broken into several numbers anyway).

Same as above. If no non-toll route is available, I would probably leave
the number unchanged.

No. The whole thing would be considered a toll route.

US 93 in AZ runs from Wikenburg to the NV line west of Kingman, at
Hoover Dam.
From there, US 93 goes to Canada, at Eureka, MT.

Close enough. 93 to Phoenix, then via I-10 to Tuscon.

I-19 does have mile markers, but they are posted so they face sideways.
When the I-10/I-19 interchange was rebuilt in Tucson, all the markings
were changed between Ajo Way and I-10. The exit numbers are still
metric based, but ADOT wants to eventually convert the highway to a
mileage based system.
