I have standardised on Merit/Hella plugs all through my RRC.
Never had one come out except when I trip over the wires at night.
I have Andersons for my rear winch plug and a little one on my inverter as the current rating is higher than Merits.
Merits are available anywhere, particularly Jaycar . They also do a combination Merit /cigarette lighter plug but I think that is spawn of the devil.
