Five (5) radios?
For some vehicles are laptop stands (two-bolt; have seen some modified with third leg for stability) which could be modified from its “plate” holder to build a
tree to hold devices.
Mounts by RAM and LIDO are where I’d actually start.
Several and to include use of the
back of the center arm console.
Where to have power enter the passenger compartment (at a 12V Distribution Panel; etc) and
How to Route looks to be the painstaking part.
My experience is that the 12V power
after panel should be built as a
harness which can be installed/removed as a single component despite a number of “legs” for best long-term reliability. Similar to how the factory would do it.
This justified the purchase of Anderson Power Pole tools & supply, for me. A short pigtail for each device.
If I moved something then an intermediate jumper to cover increased distance was E-Z.
Alternately, power distributed from a
RigRunner entails more wires, but can simplify planning as it’s then a fused circuit to
each device.
Marine-Grade wiring (type; highly flexible, tin-coated pure copper) plus Blue Sea components to manage 12V has proven successful.
Getting wiring run under cover (hidden, plus inside split-loom conduit) so that it presents no hazard of snagging by its presence is where measure, measure, measure will come in.
While I’m not familiar enough to say what brand or type,
fewer radios with expanded capabilities to reduce total number
will be the best first step.
Good luck.
