Review on Improved Camco Heavy Duty RV 30 AMP PowerGrip Male Replacement Plug - Enhanced Durability and Safety with Easy Grip (55245) by Jeremy Black

Materials of construction are hard plastic which unfortunately can easily break if dropped or hit against a hard surface. The contacts are solid brass with screw terminals. I overpotted my conductors before attaching them to the contacts. Another thing I don't like is that the body of the plug is so long that it hits the edge of the power socket and prevents the plug from fitting directly into the outlet. I think if/when this one breaks I'll look for a good one from Hubbell or similar.
