Need safer wheelchair for my Grandpa PLEASE

My Grandpa was paralyzed on his right side due to a stroke in 2017.  He has had his wheelchair the insurance bought him a little over a year now.  He has driven almost 1000 miles in it, and already had to have new tires.  He goes to all my sporting events and we ride together all summer,  Him in his wheelchair and me on my bike.  Unfortunately he is limited to the cement paths with handicap curbs.  2 Months ago his wife, (my Grandma) passed away and it  broke my Grandpa's heart.  All he has is wheelchair for enjoyment, however he wants to go places with me, he used to before he was paralyzed.  (fishing, camping, on the beach at the lake)  Since he has had the wheelchair, he has wrecked three times.  The first time he broke his right arm, the second he cut his arm pretty bad and now this time on Saturday 4/25/20 he broke his ribs.  When he got out of the hospital  I told him I would find him a better SAFER wheelchair that would let him get back to the things we love to do together .  Well, I found the perfect wheelchair for him that would allow us to go everywhere together!  These funds would allow us to by  it for him and hopefully help fix his broken heart.  Insurance will not cover  a second safer wheelchair so I am hoping to raise the money myself with all of your help.  We are so limited to the things we can do currently with  the covid 19.  This wheelchair would give him so much more freedom and let us go so many more places.  My Grandpa is 80 years old and I don't know  how much longer I will have him.  Please , please help me bring joy back to him for what time we have left together.  :)
Thank you soooo much!
