Hmm
my BD beener weighs 37 grams.

I was thinking in Newtons F=ma where a= acceleration defined as a change in velocity, which means speeding up, slowing down, or turning. "a" for a beener is actually the deceleration of the climber, but the velocity of the climber came from gravity. The acceleration from gravity is 32 feet per second squared. Weight = m x gravity which actually means weight F = m x acceleration, the acceleration of gravity (on the surface of the Earth) so the Force of a climber falling will exceed the force of his normal weight yet the F=ma equation is the same, so yes I would say it will hold your Toyota, but I wouldn't trust my Toyota to a product made by Camp, however if if has the UIAA rating then its what it is regardless of who makes it, but like I said, my Black Diamond wired beener which is ten years old weighs 37 grams.
