Abstract: A rodent obstructing system for preventing access to the interior of a mobile camper through the electrical access door. The rodent obstructing system includes a plug member having a first side slot and a second side slot, an upper opening within the plug member, and a receiver opening within the plug member connected to the upper opening for receiving a power cord. The plug member fits within the lower slot of the access door with an electrical box thereby sealing the electrical box. A cord member is preferably attached to the plug member and to the electrical box to prevent loss of the plug member.

A threaded nut is preferably threadably attached to a threaded portion of the tip member for tightening against a shaft member of the handle member. A protective washer comprised of a resilient material preferably surrounds the shaft member adjacent the engaging head for protecting the hand of a user.
