I'd like to see some more modern trucks, two types in specific. A midsize/compact truck (Like a Chevy Colorado or a Toyota Tacoma)
And a bigger truck (Like a Ford F-150, Dodge Ram, etc.)
I think a lot of people would benefit from having these as an option, since a lot of vehicles sold in North America are big trucks. I like having the more utilitarian trucks in the game too, but this would allow for a more comprehensive truck lineup.
