OK this is the story I have and theres a few ............
two years ago we went to a campground we had been to before.
the sites are not level front to back but level side to side .
I backed in >>>> this site ran down hill towards the back.
I proceded to give my then 15 yr old son the tire locks and crank handle(which he's done many times) whilst I grabbed a cold one to enjoy with the group of fellow campers .... 7 groups to be exact !
And they had been there for a day already set up and were all shootin the breeze as I unlatch the hitch and and safety chains and proceeding to jack up the trailer .
As it got to the top of the ball It suddenly popped off and the trailer started to roll backwards towards a 40 ' ravine !!!!!!! I naturally grabbed the jack and handle with both hands and tried to hold it back as both feet are sliding through the gravel ....... ONE smart friend of mine grabbed a split piece of wood and tossed it behind the camper before it rolled endlessly down the hill but not before the jack was completely folded up under my hitch which is now completely on the ground and me still trying to hold the camper from rolling by holding the jack !
we ended up digging a hole in the ground and using a small bottle jack to right the poor flagstaff .
1) let the boy pee before giving him the tire locks !
2) check to see if said boy has pee'd and installed tire locks !
3) dont unhook safety chains until tongue has cleared hitch !
4) drink more before you watch your tt roll 40 ' down a ravine !
we traded for our for our 5er 2 weeks later ...........
IT wasn't funny then but we've grown to laugh about it now !
