Body and structure: “On 04/16/2018at approximately 1:15 while traveling west on I-40 midway between mile marker238and236i heard a loud noise from the left side of the coach. I immediately looked in the left hand mirror, and saw what I thought was the battery compartment door, open, flapping in the breeze. I was approching exit236, so I exited and located a home depot parking lot just off the exit. I pulled into the home depot parking lot and upon checking the battery compartment door, found that the door was secured. What I saw was in fact, the battery compartment door skin. …”
