Has he been seen either by OT or PT. If so I would talk to them. They can teach you how to transfer someone from a wheelchair to the car and vice versa. With my mother, she spiraled down so quickly from being able to walk to being bedfast that there was never a need for a wheelchair van.

I have ordered a rollater/transport chair for my husband. It can be used either way and folded up to put in the car. He walks very slowly and has to rest often because of knee pain. I’m hoping he’ll cooperate and be willing to use it.
Good luck with your decision about buying a vehicle equipped for a wheelchair. I’m sure it will be costly.

Thank you for sharing your experienced insight. I am an eternal optimist and a preparer...there is so little we can ACTUALLY do to direct the course of our lives in this role...
