Question Bedroom Roof Vent Fan

We have a 2022 Jayco Eagle 28.5RSTS that came with a simple manual crank roof vent, no fan, in the bedroom. We would like to install a vent with fan. I removed the inside flange cover, looking for pre-wiring. All I found was an access junction for 110v. Really! No 12V? With out uncovering the 110v cover, does anyone know if there is 12V pre-wiring available somewhere up there? There is also a 1/8" paneling cover stapled to the opposite side of the 14x14 opening facing towards the TV 12v power and antennae stuff. I wonder if there is a channel or wiring under there??


I really can't believe there's not 12v wiring there for a normal vent fan like Fan-Tastic or similar fans.


Anyone know more about adding a 12v after market vent w/fan on this model?

If there is no 12 Volt pre-wire can't you just grab power from a nearby ceiling light?

I went through this exact thing on my 2020 HT 30.5 CKTS. That vent opening area has 120V, on mine at least, because it was prepped for a second AC.
I'm not sure of your exact floorplan, but my bathroom fan wasn't far away. I was able to snake new wires through the attic to the supply for the bathroom fan. I replaced my entire junk vent with a MaxxAir 4 speed vent, though it is not the remote control version.
The tricky part was modifying the existing garnish trim because I could not find a new one one tall enough to avoid a gap.

Use the wiring that is there, itís for the optional 2nd AC. Find the other end it in the breaker panel and unhook it. (Probably the black isnít hooked to a breaker anyway)
Use the wires and connect them to the 12v side of the panel. Now you have 12v at the vent.
Get a Max Air fan with a remote and a motorized cover that can stay open in the rain.
Done.

Thanks for the quick reply. Yeah - but trying to snake thru the insulated roof could be problematic. Sounds like that's what I'll need to do
