I have a grand design 22mle travel trailer. I want to add a 12 volt socket since there are none. I know I could drill holes and access my battery, but just don’t want to to that to a new TT. Is there a good place to access a 12 volt source and a good way to hide the wires in the wall/ceiling? Looking for some tips and advice if you have done this before. Would greatly appreciate any help you may have to offer.
