5 gallon propane tank(s) (Marin)

I recently picked up some free patio heaters that need work, but required 5 gallon propane tanks. Sooooo..... empty (or full 😆), I would be pleased to accept any that you might have from an old barbecue or rv that are just sitting and collecting dust. (Pictures swiped from google)
My name I Keith
I live in the valley (San Geronimo), and would be happy to meet with you or collect them from any place you would leave them out for me to pick up.
~Thank you and God bless!

I wouldn't call. I'm sorta shy and don't like answering numbers that I don't recognize. 😳
