are all the trucks the same or do they perform differently?

[Blackkennedy]

are the trucks and brands different or is it just cosmetic differences and you just pick and upgrade the trucks you like? for example kensworth better than volvo or is the performance the same between their trucks? do certain trucks in this game perform better? is there a best truck?

There may be some slight variances in the engines and transmissions, but largely they're all the same performance-wise. Just a matter of picking whatever truck suits your fancy and which you like the most to be honest.

That being said, these trucks are some of the oldest models in the game: Kenworth T680 and W900 (though I don't know if the recent updates added in some of the new cabin physics), Peterbilt 579 and 379, Volvo VNL 2014. Those in particular need some much needed care IMO, but I'm not sure if SCS will update those old models. Seems like they may, considering the W900 did get some new stuff recently, so there's a chance.

They all perform mostly the same so i just pick whatever has the most up to date model and features
For example only 3 trucks in the game currently has cabin suspension

Which 3?

it depends how your truck is configured in the shop, upgrades are not always just for visual. and what settings you have in the game menu, they are very customizable

W900 did get updated.

In terms of performance most of the trucks are just about equal with 5 outliers.

The Kentworth W900 and Peterbilt 300 series have the most powerful engines by 25hp. The Kentworth W900 has a issue with low ground clearance, so if your doing off roading - bumpy dirt roads go slow with some of the lower bumper options.
The Western star 57X does not have the 18 speed transmission but a bunch of 12 speeds which can affect heavy hauling (though not required) and is the only truck without a retarder.
The International LT Max HP engine is 565 but it does have an 18 speed.
The Mack Anthem is the lowest max HP at 505 but it does have an 18 speed.

Everything else has a 600 or 605hp max engine and 18 speed transmissions with retarders.
This is ONLY based on pure performance of a truck for heavy hauling without caring about fuel consumption.
