I'm out of PHX, and I can help you out with some answers.
I've been with OD a year and a half, the whole time out of PHX. I started in the city, and transferred to line haul about a year ago running wild. The terminal itself is less than a year old, and it's very nice. Big,141 doors, clean, lots of yard space, and it's located 1.5 miles off of I-10. The TM, ATM, city and line haul dispatchers are nice guys, and will try and help you out if they can. Moral throughout the terminal is pretty good and most of the guys are friendly.
Now as far as wild drivers, in PHX, that's only for line haul. If you're hired on as a city driver, that's what you are, a city driver. City dispatchers won't give you line haul work to do. You can pick up line haul work on weekends tho if you'd like. Being the bottom man on the city board is going to mean getting put on the Basha's grocery warehouse. I'm not gonna lie, it sucks. It's usually a 48'-53' trailer all the way full and it's 100% sort and seg. Doing that means you'll be coming in usually between 12-2pm and won't be off work till 2am or so. Bashas leaves the gate around 7:30p to get out there for an 8-8:30 appointment. Coming in at 2, you'll be running routes, doing pick ups, swapping and dropping trailers etc. prob all the same stuff you're doing now. No Bashas on Fridays which is nice.
All in all, it's a great terminal to work out of... just got to put your time in to get off the grocery warehouse crap. Good luck on the transfer, and if you have any other questions I'd be happy to try and answer them.
