the only other 2 trucks for the main characters in Season-4 for new trucks besides Jack,is Alex's truck in result of Greg Boadwin wrecking his truck truck last season and taking over Alex's old truck from Season-3 after the show was done filming,so Alex does have a different truck this season, and Ray's truck is new to the show this season too, and that Merv guy with the Maroon Freightliner Classic a supporting role character truck too for Season-4, here's Alex's truck,and somebody can get a better of it if they want, just upload this one for now though, it needs 4 stars and it was first seen in Ep.4.01
