“One thing to consider is that many walls in an RV are not thick enough for a standard outlet/box.. I believe that is why the RV version was developed... I have never had any trouble with mine.”There ARE SHALLOW workboxes which ARE designed specifically for thin walls and with a slight trimming of the mud ring they work PERFECT in a RV wall (my 1984 TT CAME with this type of box and I bought some new boxes for the extra outlets I wanted to install)..

Available
HERE for $2.35..
A shallow workbox with a HIGH QUALITY 20A outlet IS cheaper than a vampire tap outlet..
HEREfor $3.29
Cover for outlet costs about $1.00 for a Total of $6.64
A Hubbell outlet WDR15wt (15A in white) is $9.38
HEREI found the Hubbell that I had laying around..

Contact is 24ga material which is .0239 inch thickness, wire contacts on two sides so the overall wire contact area is .0478 inches

Compared to a regular screw terminal outlet which the contact area is 5/8" LONG (.0625") and two sides of wire contact is 1.25"..

So tell me which one IS “superior again”?
What would YOU rather depend on in a high current situation?
Insulation displaced connection (Hubbell WDR15) or a screw terminal connection of a standard outlet..
I WILL take the screw terminal ANY DAY over the Hubbell vampire tap..
