My wife who reads and sometimes posts on FR was driving. As we entered a curve in the road the truck started to rock. She couldn’t stop it from rocking and it tipped over and slid down the road.

Glad to hear you're OK. But what the heck happened? A one-ton should be plenty of truck for that camper. Any idea what caused the rocking?

We entered a curve in the road and it started to rock. From then on each new tip was stronger than the last. It was like a harmonic resonance like the Tacoma Narrows bridge collapse.
