I've just done a ton of research on this for my truck, so it's apples to oranges. But I'd go with a Tarheel 400 antenna with TurboTuner2 mounted on the rear, run your wiring in cable loom along the inside of the frame rails. Use a radio with a remote head like the Icom IC-7100 or Kenwood TS-480HX and install the base in a cabinet near the floor somewhere so you can easily get the cables up from under the unit. Run the cables to the head on the dash however convenient. Mount the head to your dash with Ram mounts. Kenwood requires two power harnesses for the TS-480HX and the longest ones they sell are 23' long. I'm also powering everything via the ignition and an aux switch via 30A relays for each leg and diodes to keep current from one trigger from being sent down the other.
