I've been having issues the last few years with the regular cigarette plug in the back of the landy where the plug would loosen over time and create just enough of a gap that you lost power to the fridge. Of course you wouldn't see it by a casual glance.

I've not checked the manuals for the Dometic fridge but I'm wondering if this plug would be sufficient or should I go bigger with say an Anderson plug? What have others done ?
