Little off topic, this is something that is quite common to see (at least in Indiana). Usually, folks are loading up to take their boats to the water. At this campground, the water was about 5 miles away. I've never seen anyone ride in a boat on the highways, but quite common at State Parks and State Recreation areas. Maybe they think there is a difference driving 30 mph than 60 mph. And yes, I've seen inflatable "toys" flip out of the back of boats on the road, and the kids scrambling to try to rescue them. Very scary to follow them in the truck when this happens.
I've never heard of anyone ever falling out of the boat, but still, it makes me cringe every time I see this. Sometimes, kids are hanging over the edges, climbing around, acting like monkeys. I understand the excitement, but sometimes common sense IS thrown to the wind! It's not just RV's here. THIS example is very common, much more than riding in an RV.
