We have a 2008 Sunset Trail travel trailer and when you push the switch to put in the slide in sometimes nothing happens and sometimes it works a little then quits. Could this be the switch, cause it seems the power is there when we checked it.
could be the switch, could also be the thermal self resetting breaker. These are usually mounted outside on the trailer frame and are prone to corrosion. It could also be a week battery. lots of things to check. Do you have a voltmeter?
