With the SVC Tower, we can have it setup for pods or lightbars. We have mounted a 40" light bar on a actuated setup, while you can squeeze a 50" onto a non actuated setup.
Wind noise is usually not an issue with bed mounted towers as they sit behind you, so any wind noise they do produce, you most likely will not notice.
Wiring is fished through the tubing of the light rack, and through the bed, which then you can either run under the cab and into engine bay/firewall, or push through floor under door trim and run wire under carpet/door trim.
SVC towers can be setup as a fixed position, or can you can opt for manual or electric actuators to flip up/down.
Shoot us a PM, I would be happy to get you setup for a great deal on the SVC Tower and lighting package!

Edit:
Here is a SVC Tower that we had retabbed for a customer to hold a 40" Baja Designs lightbar on a dual electric actuated setup. Previously held 5 cannons.
And here is an example of a fixed position setup with cannons.
