Broadway FB 12v Wiring Problems?

I'm not familiar with the current Peugeot vans so have no idea whether the running lights are a Peugeot or AS installation.

I suspect however that your reversing camera is powered light the Mercedes from the fridge supply in the Sargent EM50. The fuses on the EM50 have no guides for the fuse blades so it is possible to have one end of the fuse in its contacts and the other end touching the outside of the contacts. All seems well but as you drive flexing makes the contact intermittent and the fridge (which you don't notice) and the reversing camera operate intermittently. I have had that problem.

The EM50 is a grey box usually located somewhere behind one of the front seats that has a plastic flap with a red indicator light and nine fuses underneath.

I've just had a look at the info on the unit and F2 is for the marker lights and F7 for the fridge so I would inspect them both carefully.
