I couldn't even narrow it down, honestly. Although we were all born and raised in NYC, if you bring any member of my family camping, their inner redneck comes spewing out.

For starters, my father likes to tie his boat to his jeep, then pull it through a field, while people drink on the boat. No trailer is used, it is literally dragged through a field of grass and hay. Usually my father will have the car in cruise control, sit on the top bar, and steer the car with his feet. It isn't a big boat, a small 6 person motorboat, and he removes the motor before hand.

Another thing they like to do is tie a hood from a car to the back of his jeep, then try to surf it around the field. They had to cut that out after somebody drunkenly turned too fast, and my sister was flung into a tree.

One time my uncle found an old washing machine on the side of the road, so he brought it home to try and fix it. When he couldn't, he filled it up with some flammable liquid he had, put it on the roof of a shitty car they had bought to destroy, then shot at it. After a few shots, nothing happened, so he walked towards the washing machine to investigate. Maybe 5 feet away, it blows up, knocking him down. After a few seconds, he got up and started swearing. He was angry that he spilled his beer, and he'd have to go grab another one. Having to drive the car with a mostly collapsed roof to the junkyard a few days later was pretty funny, too.

There is also a decent sized pond by the campsite, and they enjoy driving on it during Winter, doing donuts and whatnot. Its all fun and games until my uncle drives his backhoe on the not-quite frozen pond, then falls through the ice.
