12volt while towing

[campernurse2012]

Hello ,
We have a 05 2619 and I’m adding a digital wireless rear view camera to the back of the TM . I’m thinking of running a power extension wire from the camera which will be mounted on the back of the AC shroud (for the birds eye view )down underneath the front shell to the cigarette lighter plug near the fridge , what I don’t know is if the plug is hot while towing , if so this would be ideal since I wouldn’t have to drill or tap into any wires.
Thanks for any and all help in this matter.
