I haven't seen the interior of the Tacoma '05 yet, but I have an '04 PreRunner Double Cab that I've been working on for a while. My install is still in progress, but at the moment I've a custom console sitting on top of the large cupholders in between the seats that hold my Icom UHF & VHF commercial rigs and the Syntor x9000 lowband head, with the Kenwood D700 head hanging off of a custom overhead console.
What model (standard, extra cab, double cab, auto/manual, etc) do you have? Any idea what kind of lighting/strobe loadout were you thinking of? And do any of your rigs have remote heads?
Found some pics of a '05 here

Looks like there might be some storage space under the rear jump seats. There's also presumably space under the front bucket seats, and the possibility you could mount stuff on/in the overhead console.
One great resource is the Toyota TechInfo website:
http://techinfo.toyota.com It's a subscription service but you can access documentation on every part of your vehicle, including how to take bits of it apart to run wiring, where terminal and fuse locations are, etc.
Feel free to PM me if you like, and I can share some tips I've learnt from my install experiences.
