Hot-Skin condition is what causes a tingle when you touch the doorknob or metal steps of your RV while standing on the ground. YIKES…that doesn’t sound like much fun. So if you don’t ever want this condition you need to make sure the frame and body of your RV is never electrified due to poor maintenance, bad connections, or a hot ground in a power plug. Usually this happens when a campsite pedestal outlet is defective (unbeknownst to you) or if you’re using an improperly wired extension cord. A sure fire way to prevent Hot-Skin is to use a Progressive Industries Surge and Electrical Protector EMS models. They offer some ubberly awesome models so find the one that is right for you and your RV.
