G'day smutty,
I recon I would run A Higher Rating fuse, and probly go with the 20 or 25 amp.
The reason I say this is, What are you protecting anyway....I asume its the supply line to to rear of the vehicle, incase of shorts etc etc, A 25 amp fuse with blow very rapidly if that occurs.
Put the fuse right at the battery so if you get a rub through on the cable you are still protected (amazing how many people put their fuses at the rear of the vehicle).
Anything you plug in should have its own protective fuse anyway.
To small a fuse in the supply line causes all sorts of nusance tripping of the fuse, such as varing loads presented by the fidge, surge currents etc etc.
And as sujested above a thermal circuit breaker (resetable) on the supply line fitted right at the supply (battery) is by far the best option.
Anyway good luck,...
John
