Volvo and Mercedes (freight liner) trucks are popular in the US. Truckers tell me Peterbuilt makes a good truck and compete well, but since I don't drive a truck I can't tell you what makes them better. I can tell you that Volvo and Mercedes are considered basic trucks for companies to own, while those who own their own truck like pay extra for luxury features in a Peterbuilt. (the only luxury I can see though is chrome decorations, again not being a trucker I have no clue if anything else is better or not)
