Daifly,
Many years ago I did a lot of ambulance flying in Hawker 700's and never once had to use the overwing exit for loading. Also this same plane would be put back into exec. config very quickly. The medics on board always used to prefer the 125 over the Lears because of its extra space and headroom. I've never flown a Lear but for the description given at the top of this thread I would think a Hawker is hard to beat.
Cheers.
