Instead of installing a splice box to make the connections between the Romex and the extension cord cable being held in the photo, they use these quick connectors, and I have seen quite a few posts in the past where these have failed. Yes, this would be another thing to inspect on these rigs, along with checking all the connections in the panel, 12 volt and 120 volt, and all the fasteners on the suspension, and numerous other things.
