holes in roof
don't know if you are planning on running out of the hole(s), but for me would find another way to run your wires/cables etc. sounds like you are planning to mount some antennas on roof, I believe your unit is already 12'6" tall and putting anything with height might really put you in a bind when you go into places like gas stations etc. best of luck.
