Handicap van for Brayden

My 11 year old nephew has been diagnosed with Duchenne Muscular Dystrophy. It is a degenerative disease for which there is no cure. He has been in a wheelchair for about 3 years now and has only had a manual wheelchair so far. Not too long ago their insurance finally approved for him to get an electric wheelchair!!! What a blessing that will be! He will be able to have the freedom he hasn’t had in years! My sister is hard working and takes care of Brayden almost completely solo. Brayden’s dad is serving in the Navy and is currently deployed. While the wheelchair is a great blessing and huge benefit, it does not collapse like his current one does so they have no choice but to purchase a handicap accessible van. The vans are not cheap and can run upwards of $50,000! I am hoping that we can help them get a little money so the incredible blessing of the electric wheelchair won’t cause a financial hardship. Every penny counts! Thank you so much for your help!
