DS in MO and PAM

So i've decided to join this forum and post some thoughts and questions about what've i've been reading. Due to a separation, I've decided to pursue a lifelong dream of becoming an OTR driver. In doing so I sent an inquiry to DS and I'm interested in driving for PAM. My only other option was USA Truck. Here's my expectations:

1. School lodging will probably standard at best
2. As long as I listen and take good notes, the course should be adequate.
3. Upon graduation my driver trainer may or may not be suitable for me, at which time I can contact someone and request a trainer that I can get along with
4. Upon completing my training, I can expect to be put into an older unit (not ancient, but but not brand new)
5. As long as I keep my driving safe, my schedules on time, and my safety up to par, I'll be satisfied with PAM
6. Although I'll more than likely get the crap loads, eventually once my rep as a driver goes up so will the quality of the loads.
7. I'm newly single, so I'm not at all worried about being home on time or whatever.

Now having said all that I have a few questions...

1. The "in cab view" of the trucks, is that fairly accurate? I'm not concerning about the ammenities (tv, laptop) I'm interested in the appearance that was given.
2. Which is worse, snow or mountainous driving?
3. After putting in your time as a new driver, what can you actually expect to earn working for a trucking company?

Thanks for any posts that may arise...
