If your drilled rotors are the same size as the OEM blank rotors, they will not cool as well as the plain ones due to less metal mass to dissipate the heat. The holes are not there for heat issues. They are there to allow the gasses that form between the pad and the rotor to escape. However, that is not a big deal these days with newer pad materials. The cooling comes from the metal mass of the rotor, the internal veins of the rotor and and air ducting. In short, you get less cooling with cross drilled direct replacement rotors.
I would not personally do any heavy towing with drilled direct replacement rotors.
