Haha, all classic videos, and I have honestly considered a water slide. In our former town there was a slow moving predictable river, and many of the guesthouses constructed slides and water play equipment. Because of the whitewater and flash flooding here, any water equipment would need to be on a pulley system or tracks so we can lift out of the river when not in use. I'd love to have a slide with the lower half retractable like a draw bridge, a dream maybe one day that can be fulfilled.

You're right about the sun, I have employed some parking techniques that help a bit. But the biggest news is that yesterday I think I saw an abandoned road in between two rubber tree orchards. It would be a cooler and more protected place to park, so I will investigate more next time I go.
