Experienced, but new to OTR driving

Hey guys, I have some questions so I thought I would start my own thread. First off, I've been working in the construction field and am used to this enviroment. OTR is kind of "uncharted territory" for me, so-to-speak. I've pulled end dumps, belly dumps, and moved heavy equipment around with a lowboy. I've also drove dump trucks and concrete mixers. I've spent most of my time in day cabs hauling rock, sand, rip rap, etc.
Anyway, a few weeks ago I landed my first OTR job. I gave my 2 week notice at the job I'm currently at and start the OTR job on January 4th. I'm going to be issued a mid-roof Freightliner (Columbia I think) and will be pulling vans and pneumatic bulk tankers throughout the mid-west. The company's training period consists of the trainer driving his truck and me following in mine for a period of 2 weeks. During this time, we load together and unload together, with him showing me the ropes on the pneumatic tankers. As far as the van training goes, they just give you map and tell you where to go, along with any special instructions on what to do once you get there, etc.
I plan on stocking the truck with tools, a week's worth of clothes, my laptop, a small scanner/fax/copy machine, coveralls, toiletry items, my GPS, CB and speaker, as well as a set of jumper cables and a tow chain. Can anyone think of anything else I should throw in? I've got a 50ft air hose that connects to one of my glad hands too that I plan on taking.
Thanks.

 

Ok. When they hired me, they told me that pulling the tanks I will be home pretty much every weekend and 2 or 3 times during the week. Pulling the vans, I will be home most weekends, but won't have any pit stops at the house during the week like I will when I'm yankin the tank.
