I have just changed my double two pin sockets in the galley as I noticed they were getting too warm when running a fan heater one day. I replaced them with CBE Sockets which is straight swap for the existing ones, same size so no extra holes to cut etc. I got mine from camperworks.com as they are the same as used in motor home and caravans. End result is excellent and no more adapters, now I will change the rest out.
