I have had all of the vehicles you can imagine. Kids sleep in the wildest places, I love it. I wish we could all be more like children. There are so many things we can learn from them, they have not learned the wrong way to do things. Movement patterns for example.
The one that got my kids no matter what, any drive longer than 10 min and they were asleep was my 79 Ford camper special. 460, 35” mud tires, 3” flowmasters dumped under the bed. The drone of tires and big block was the song of cruise snoozes.
Also skreddy 40 thread needs some love. I haven’t seen it in a while
