Realistic behavior of suspensions and modified physics for the trucks. Breaking feels more realistic, also taking curves hauling a trailer is more realistic, you feel more of the trailer. Driving in rain ( though very rare on the default map ) is a bit more slippery at high speeds.
Note: truck behavior changes depending on the trailer and its weight.
