I want to add a light to my holding tank bay so I can keep it from freezing this winter. However I discovered what I thought was the second outlet is blocked off somehow. it seems solid. but I'm not sure the purpose of that kind of a plate.
Has anyone seen an outlet like this in an RV and if so is that actually a knock out of some kind or is it really meant to just look like a fake place to put a plug like that? I'm not sure how to open it up but if anyone knows that would be great. Currently the only open plug I need for my converter so I cant spare it since I was going to plug the lamp into a thermocube to turn it on only when needed.
