I've know of several operators of the 6000 and 7500 that opted for the standard crew rest seat that fully reclines flat with a bunk above it so 2 crew can lie flat, or 1 can sit while the top lies flat. I've also seen the first 2 club seats on a 7500 sectioned off for crew rest.
When 2 fa's and 3 pilots are onboard a 7500 I would imagine those with only 1 lie flat crew rest seat must also occupy a cabin seat for rest?
I find the VJ config very strange unless galley divan turns into a bed.
