Here is an example of a basic lighting circuit. You will typically have multiple bulbs (or outlets) in parallel. Nothing very magical about the operation.
I would go to the light switch and see if there is 12 volts available there. Measure to a metal ground unless you see a ground wire in the outlet box that you can measure to.
If you measure 12 volts there, the problem will be downstream from the switch to the lights. If you don't measure 12 volts there, the problem is upstream between the switch and the fuse panel.
Do any lights come on when you flip the switch that controls the ones that aren't coming on? If so, go to the outlet that is working and check the wire connections in back. The light string will be daisy chained so the link to the next light may be bad especially if they used crimp connections.
Are these LED lights that you installed? If so, they are polarity sensitive and will only light when the positive and negative leads are connected properly.
Lastly, I have no idea how Jayco connects the negative side of the light string. If they tap into a metal ground somewhere, that may be the problem. You can try measuring for 12 volts at the socket to a metal ground. If it is there you may be missing the ground side.
So, the problem may be in the 12 volt positive feed or the negative feed.
