I have an oversize wheelchair & 2 walkers I want to donate as my husband has passed away. Any suggestions?

Catholic charities.
they provide these (when they can) to people in need, and very often get them back to lend out again,

also, Salvation Army. They sell them very cheap, and donate where someone can not afford them at all.

pay it forward.

Wheelchairs of Hope might be a good start, or they can direct you. It is so kind of you to think of others that may need assistance.

Your local non profit is another idea.

I think the liability issue arises in facilities or places that need to be concerned about that possibility.    I don't know how Senior Centers address that issue, or if they don't, but in my area they do have loaner closets with equipment available.  

Some neighborhoods also have their own share, sell and/or donate groups.  

Another possibility might be VFW or Paralyzed Vets.   I believe the VFW also takes donations, on a kind of impersonal basis.  Apparently you sign up online for a pickup; I only did a quick search so I don't know if there's any human contact prior to pick up or if they just come.

Purple Heart also takes donations, and picks them up, as does Salvation Army.

I don't know what the LV is, but have you tried Goodwill, any AL or NH, senior center or your local yardsale /craigslist sites? Maybe a firehall ( for use during bingo or dinners when some people forget theirs) or church? I see them on our local yardsale sites all the time, I am sure someone could use them. And before anyone starts.. I know some places will not take them due to possible liability issues, but there are lots of folks out there who just NEED one and can't afford one new
