Trying to get rid of electronic medical bed, 2 wheel chairs, walker, bedside toilet and in home oxygen tanks. Any suggestions?

Contact local Senior Centers and see if they're aware of MOW clients who may need them.

I prefer FB Marketplace over Craigslist because usually you can check out the person who wants to buy the item.

craigslist, nextdoor.com etc.

I see them advertised on Facebook Marketplace all the time. You can also call your local Veterans hospital and ask if they accept donations.
