Advice on wiring up a fridge and work lamp.

Just run a single wire from battery to the sockets.

You MUST have a fuse at the battery which must be no more amps than the rating on the wire, in case there is a short anywhere along the wire.

You could put additional fuses to each socket, so that if the worklight shorts out, the fridge keeps going.

Run 50amp twin core wire from the aux battery and don't try earthing off the tray.

Use a auto reset breaker close to the battery rated at 50 amps and use fused sockets on the tray. Best to buy marine grade if they are in the weather.

Gareth. I suggest running twin double insulated 6mm cable (or bigger) from the auxillary battery through a waterproof 30 amp spade fuse holder connected directly to the terminal. Keep the wiring as short as possible to minimise voltage drop. Ideally this could connect into a heavy duty power outlet then be looped out & run to a 2nd plug for the lights. (4mm would be ok for lights)(clipsal 32 volt plugs are excellent). Avoid cigarette lighter type plugs as they vibrate out & often melt.
Running the earth wire from the battery eliminates poor connections through the body work particually over time when things start to rust.
The fuse at the battery should be no larger than what your load usage requires enuring that if the positive wire was to rub through onto the body it will blow & not set fire to the wiring. A 20 amp fuse should carry the load fine.

On my own 4by I've taken it one step further by running 16mm twin cable from the battery in through the cab then out to the rear bumper into an Anderson plug. This is either an external power point for assesories or power into the caravan. I've then tee'd off the main cable at various points for power to the CB's, HF, fridge, light plugs, compressor, GPS, shower & diff locks. Individual spade fusing of the appropiate size is fitted where I tee off. This system minimises voltage drop & mutliple runs of wire along the car.

It must be the Christmas spirit - if only it could be like this 52 weeks a year :-).
