Harry and the Hendersons-like creature photographed outside couple's RV

From (Link: bfro.net) We were getting up early to hitch up our travel trailer and start home to Oklahoma. My wife had gotten up first and then I got up and went into the bathroom. My wife opened the door and said that someone was standing outside the entry door to the bedroom of the trailer. I went back to the room and saw a large shadow in the window. The window is privacy glass so they couldn't see inside. I could see a chest, a head and about half of the arm. I reached into the night stand a took out my pistol thinking that it was someone. I then started toward the back of the trailer to the main entry door. While I was doing this my wife thought to take photos. She took 3 photos which does show the shadow of whatever it was very well. When I was at the other end of the trailer I opened the door and turned on the outside light at the same time. There was nothing there, I did hear what sounded like someone walking very quickly in the distance. I went around the trailer but couldn't see anyone. It was at this time that I realized that the window on the door is too high for someone to have been standing there. I took pictures to show how high it is. We waited until daylight to go back outside, I looked around the front and side of the trailer and noticed what appeared to be large tracks in the gravel. I took pictures of these. My friend who is a photographer took a copy of the pictures showing the shadow in the window and enlarged them while trying to keep the clarity and it is possible to make out some of the features. His exact words are " it kind of looks like Harry from Harry and the Hendersons". I don't know what it was but it was very strange and the photos are quite interesting.
