NMO roof mount antenna

Just purchased a 2009 Double Cab Tacoma. It has the satellite radio antenna. I want to install a roof mount antenna. I am thinking installing it near the dome light for access to the underside of the headliner and then running the feedline down the passenger side door port. Anyone drill through roof and run into any troubles, driling through wires, running into roof support beams etc?

I know BJMoose has done this. But after looking thru his write up, I see he has a regular cab.

Maybe you can get a few ideas?

 

Thank you. That is a well documented installation.
