A question about working within the RAF?

I am planning to apply for a personnell/admin job in the RAF. It's occurred to me that I will most likely relocate somewhere in the UK or maybe even outside of it. The fact that I dislike my current job and feel that there's nothing really good going for me here in Edinburgh makes it seem even better. Can anyone who has had experience of working in a the personnell dept of the RAF tell me what I would expect? What are the average working hours? how often would you be able to go home? Are you given free accomodation? are you given free meals? Would you be expected to take on minimum training ie fitness? The website doesn't cover a lot of the things that I was hoping to read. Thanks
