Designer 35RLTS and Jayco Talk...Thanks Frank!!

Ok everyone I have a question...

Plan is to add a small TV into the side compartment and swing out on an arm when needed and we are outside...already added a power strip to the roof of the inside compartment (thanks Loyd for the suggestion)...until I can buy the swing out arm how do I get a TV line going down into the compartment so I can hook it to the TV so when we have either cable or just regular TV I will be able to access it down there also?
