A number of years ago while Working on the road in southwestern NY, I was camped in a small mom&pop park. During the week I'm early to bed/early to rise and about 8:30 pm I was putting away the evening's dishes and getting the coffee pot ready for the morning brew when a new neighbor, an older couple, with a TT pulled into the site next to me and began to set-up. Thinking nothing of it, I turned in at 9 and went to sleep. I'm a hard sleeper. Sometime during the night, I was semi-awakened by what sounded like a blood curdling scream and what seemed like a thud. Thinking I was dreaming, I went back to sleep without further investigation. I rose with the alarm and made coffee, poured a cup, and headed outside to watch the sunrise. Next door there was a truck at the front of the site, but no trailer. After further observation, I saw a 22'-23' TT that had slid completely off the camping pad and came to rest against a tree about 15' behind the pad in a wooded area. Both the electrical plug and the water hose were extricated from their moorings.
Shortly after sunrise an elderly gentleman exited the wayward camper, walked up the slight embankment of the RV pad, bade me a good morning and apologized for the ruckus earlier that morning. Said, he'd been camping in that site, at that campground for the last seven years and he never needed chocks. Said momma had arose earlier that morning to visit the potty and while she was there, the TT decided to, um... relocate. Said he was heading into Walmart later that day to buy some chocks and a new water hose. A nice old guy, but I sure felt sorry for the wife. She must have been absolutely petrified while sitting on the throne. Chock those tires!
