Only visited 'Credenhill' for a short period for ATC Camp back in '84, but I would have thought the available open space (south of the hangars) at the ex RAF Hereford was a bit small for the V22; Ok for the helicopters they presently use though.
Edit to add: In fact looking at a satellite photo, I'm sure there are more hangars there now, so the open space is even smaller!
Plenty of space where the CRW training takes place
