The biggest difference I have seen in any receptacle in my previous RV's have been the type that the wire slides into a slot in the back, kind of like the old Christmas lights or yard lighting. The GFCI Receptacle should be standard as any household type. The box may be different, shallow ones are used in some applications where wall thickness is an issue. Be careful and if you are to replace it yourself, make sure you follow the guidelines on the packaging and understand the load side of the receptacle. Good Luck and Be Safe ! ! !
