also, a thing to note is they changed the way how dealerships handle trucks. means nothing except no more mod conflicts for now, makes you wonder what they have in store.
my speculation is they got either Western Star and Freightliner (and a Detroit Diesel engine) or Volvo and Mack.
for the trucks in the poll, might as well show that trucks in the poll
International Prostar

International LT

International 9900i

New Cascadia

Old Cascadia

Western Star 5700

Western Star 4900

New Volvo VNL

Mack Pinnacle

Kenworth T880

Kenworth W990

EDIT #1: seeing as International is going to be the next company, lets speculate on which model is coming
EDIT #2: the VNL is the next truck for ATS, and a Freightliner Cascadia Model has been shown by Carthoo
EDIT #3: been a while hasn't it? well, removed both the Lonestar as it has been released (I'm late, I know) and removed the Mack Anthem (coming on 4/28/20) I wonder what the next truck will be. also uploaded a new image for the Prostar
