Donation Purgatory?

I live in Orange County, CA (near Camp Pendleton/San Onofre) and I've got a twin bed, dresser and office chair (all in good condition) that I am trying (present tense, still searching) to donate, preferably to DAV or an affiliate (screw the Salvation Army, their overpriced thrift shops, and their fundie indoctrination masquerading as drug rehab).

So far I am having trouble even finding anyone to talk to about this. I'm no Google dummy -- there's plenty of websites, but all of the places I have seen thus far don't have an easy way to schedule a pick-up (I don't have a suitable vehicle) or a way to speak with anyone directly.

Anyone with ideas? Experience?

If I have to rent a truck, this stuff's going to the landfill, which would be a shame.
