I don't smoke and won't allow it in my car, so I don't need the ashtray. Since the cigarette lighter is attached to the pull out tray with the ashtray, is it easy to take the lighter out of the tray and take out the ashtray out? I want to retain the lighter for power, in addition to the one on the passenger side. I'm thinking of mounting it farther back, as I don't need the lighter feature, just the power feature. Is this doable?
