I took a chance. My 2006 RV had a Winegard combo socket just like this - cable TV and 12V DC socket - but the 12V socket was too narrow. All you plugged in was a 10 minute struggle to then remove until almost the entire panel was pulled out of the wall. Newly ordered, fingers crossed and yes! The socket has changed, allowing any 12 volt plug to fit snugly and then be removed without swearing.
