The answer to the question is: No rack install today.
On their second try [Tuesday & Thursday], the technician at Leonard’s did not drill through the roof above the cab. Further, I was told Tuesday they had drilled through 2 holes–NOT! Just one! I am sorely disappointed with the outcome of their work. There are other problems; but, I will not write about them here.
I purchased Cobalt Bits which are supposed to be tough. I tried for about 5 hours and also did not get through the roof. I must now penetrate 5 of the 6 roof holes above the cab.
Next, I will try Tungsten Carbide Cutting Bits. This may take a lot longer…
