We have a crawl space beneath a bedroom with a waterbed. I'm thinking of
wedging in a few 2x4 struts beneath the center of the bed to transfer the
weight load from the rafters to the ground below.

Good idea, bad idea or what?

If the house is well built, it would not been needed. OTOH, if it makes you
feel better, why not?

I'd use a piece of pressure treated 2 x 4 and set it atop a brick or
concrete paver.
