David.
All the discussion, and photos (to say nothing of all your work) with the gurney, explain why the newly tooled gurney, in the 59 ambulance kit is so narrow. I'd thought it looked too narrow when I watched HPI Guy's video, but now I see why it looks the way it does.
Round2 wisely made it fit the kit.
The work you have done on the Surf Shark is just stunning!
