B's Ride: To purchase a ramp van

We are trying to raise funds to purchase a ramp van for our 8 year old son, Benjamin,who has spinal muscular atrophy. It is a neuromuscular disease that causes severe muscle weakness. He cannot walk and requires a wheelchair to get around and we need to get him a proper vehicle to travel around in to his doctor appointments and visits with friends and family. Right now we lift Benjamin in and out of our current mini van, but he is getting heavier and it is getting much more awkward to get him in and out. For his own safety and freedom a rear entry ramp van would benefit him and his needs. Ramp vans cost upwards of $60,000.00, which is a very expensive vehicle, but we truly need this for Benjamin.  Thank you for any help you can offer and/or for sharing this link!
