First of all tell the kid to get down NOW!
Second tell him that he can not climb up the latter !
Third tell his parents to control their child !
You should not have to do anything to your camper, if the parents can not control their kids then ask the to leave. We have have a number of grand kids, we both tell their parents that if they can not control their kids we will while they are on our property or house or camping with us.
I might sound like a mean old grumpy man but my wife agrees with me, if you can't control your kids then don't bring them around our house nor camper, we paid allot for them unless you want to buy them or fix what you break .... gurrrrrrrr
