A handicapped van for Stan

My dad was diagnosed with ALS 3 years ago. Over this time he has lost the ability to walk and now relies on a power wheelchair to get around. He can no longer hold himself up so this makes it difficult for my mother to get him into a regular car. This means that just to leave the house takes the help of others on both ends so they rather not go anywhere at all which can be very isolating and lonely. I'm looking for help to raise funds for a wheelchair accessible van to give them the freedom to come and go as they please so they can enjoy simple things like going out with friends.
