Free would be nice but willing to buy.

I'm asking a lot but modern,foldable and liteweight would be preferable.

Thanks to any who can help.

Sorry, I don't have a wheelchair to offer you, but if you find the need for a wheelchair/scooter ramp for the rear of a vehicle, I have one for sale. Has pull out ramp and folds flat to the rear of the vehicle. Brand new.

if it's not a long term situation, check your local Elks Club and Senior Centers as they generally have equipment that you can sign out and borrow on a short term basis
