On ours (not a Jayco) the 7-pin green wire is for "Running lights and licence plate" (could your ground be lost at the licence plate?)

No. Different leg of the circuit.

The "running lights" are what I call "clearance lights." I don't know on ours if they are split into groups by location, what a nightmare
:(. I don't know what the OP means by "parking lights" either.

I've been using the terms somewhat interchangeably. As far as the camper and wiring are concerned, the clearance ights, marker lights, parking lights, and running lights are all one in the same. I personally refer to the two amber ones at the top corners of the front cap, the two red ones at the top corners of the rear cap, and the three in the top center of the rear cap as the 'clearance lights,' while the lower ones down the side and the ones in the rear park/brake/turn housings collectively as 'running lights', Parking lights', or 'marker lights.'

As a quick fix, if you want to go camping, can you get at the ground for one of the red lights at the back and run a wire down the back ladder to the frame, taping it to the ladder so it stays there? (Assuming that one working would light them all up as suggested above)

No back ladder to run it down, and a wire left dangling down the back of the camper would not work for long, let alone trying to seal it against the elements. That's why I was thinking the compartment behind the tub surround may provide enough of a cavity for me to fish a wire from the upper clearance lights down to the taillight to share that ground connection.

My temporary fix is to only travel during daylight hours for now. :)
