The nearby trailer door is locked and can't be pried open, but a peek through the window reveals a floor hatch. Move the wood by the stairs and enter the hole it was covering, then crawl to the hatch and enter the well-stocked trailer.
Poke around a bit until you're faced with a major decision: Side with the kids and stay the night, or side with Kate and get back on the road. I chose to stay the night, which results in a conversation with Kate. While retrieving the gas can...

Javi sees that Kate and the kids have fled via the floor hatch, which you can cover up with if you're quick enough. This isn't enough to keep Kate and the kids from being detected however, and...
The chapter ends with Javi being knocked unconscious.
