Freightliner. I always get the full extended warranty.
Anytime it's been in for a warranty issue, they never give me a hard time about it. They don't try to weasel out and get me to pay. I've been to many dealers in Canada and the USA and they always take care of me.
Even got a whole brand new engine after a thrust washer failed with only 35,000 miles on it. Although that one did take 11 days to replace.
