If you replace the sockets with screw terminal ones, make sure to check from time to time that the screws are staying tight. Vibration in an RV can tend to loosen screws. For much the same reason, it's not a bad idea at all to tape wire nuts in RVs even though it's not generally necessary in fixed houses.
I think the type of connections that get back wired and then clamped with the screw and a plate (not the spring clip back stab outlets that hardly stay tight in ordinary houses) would be preferable to the screw terminals you wrap the wire around for RV usage.
