Need tips on buying tractor and general O/O stuff

Couldn't find anything on their website regarding purchasing a tractor, and they still haven't replied to my email, so I guess that was a dead end. As a starter, I'll probably try to find a Freightliner Columbia. A few of the drivers I've been talking to say they are cheap to maintain, and a little more fuel efficient (and doesn't look half bad with a mid roof).
I looked at the glider kits and saw that I can get a current year model with a brand new pre emissions Detroit engine, so that will give me something to work towards later.

 

05 century is what I've got now, but it's the full size sleeper for pulling refers and vans.

I really like the look of the 587 from Peterbilt. Hopefully they will be offered as a glider later down the road, when I'm in the market for one.
