Stupidity: The broken-down RV was on a slight upward grade. Olivia asked her mom if she could use the jump rope, and her mom said "yes" but to stay where she could see her. Olivia went behind the RV's rear bumper to jump. Her mother was sitting along the side of the RV, facing away and could not see Olivia. Even if a vehicle/RV isn't broken down or being worked on, children should not play behind vehicles. Olivia's mom ignored her and the out-of-control RV slipped into reverse and ran over Olivia.

Stupidity: Drake's bike fell over on the sidewalk perpendicular to the parked RV, not far from the middle door. It would've been hard for someone to miss seeing the bike when near or in the RV. When Steve went to get his dog Bentley, Drake's mom drove up and asked if he'd seen her son who was riding a bike but didn't come home last night. Steve didn't bother telling Drake's mom he was going on vacation, but said he'll "keep an eye out." Steve still didn't see the bike on his way back to the RV. (00:04:30 - 00:07:00)
Stupidity: When Olivia said, "Momma. It's hot", she was wearing a long-sleeved shirt over her overalls and shirt. Her mom, wearing a sweater over a tunic top, replied, "I know, baby" and asked Steve to turn the A/C on in the RV, but the A/C didn't work. Instead of removing some layers, Steve opened some windows. Jay complained how hot it was, but he wore a hooded sleeveless sweatshirt over his T-shirt (and never took it off, even when outside in the desert). (00:09:31 - 00:46:00)
