We have , or did have one here on the Island, not the same set up though. Ours is just a big ambulance that takes patients from our little hospital, over to the mainland for Ops. they don’t do here. I went in it when I had my heart “event” a few years back and the crew were just great, very caring and attentive. it holds a couple of stretcher cases and about half a dozen wheelchair jobs. Haven’t noticed it about lately though so hope it hasn’t suffered from cut backs! I will endeavor to find out.0
I can now report that we have still got our Jumbulance hear on the Island as on Aug.12th I had another Heart Attack and on the 15th found myself being loaded in it again for a trip to Portsmouth, where I had another Stent put in. It is five years since my first one, so wasn’t really expecting it, but I don’t think it was as severe as the first, and am now back home to start on the road to recovery ( I hope!) already taking short walks etc. I have to say the crew on the Jumbulance were as brilliant as ever, as were all the staff who cared and attended me. I doubt they will see this, but a Big (G) thank you anyway. 
Looking on the bright side though, all the re-hab stuff is familiar so should be a breeze! and I feel I should be able to get to pretty normal a lot sooner this time. (fingers crossed)
