Here is the problem. Fan/Light in living area in the 2009 - 3055 Bighorn is not wired for AC Unit. The only way I see to get 12 AWG copper wire and 12v wires to this area is to run the wires through the AC duct. What are the reasons, if any, for not doing this? Is there a code or regulation addressing this? I'm open to any other suggestions or solutions.
