3 years old 375000 km so far. Problems so far, I had the transmission go at 300 000 km only 2 1/2 years. Sounds like a P2 failure. (Usually Drive line out of aliment but mine was in spec.just checked 3 months early when steady bearing was replaced hence why i'm still fighting about warranty 11 months and $11 000 later. I just talked to the Western Canadian Service Manager 2 days ago. Its gone all the way to the US office so far. Other than that mostly wear and tear. 1 steady bearing Diff seal wheel seal. I've gone through 7 shocks but first 5 were covered by warranty although I think the last 2 should have been they disagreed. they changed the first 5 during the first 2 years. the last 2 were replaced in the 3rd year but only 1 year after they replaced them last.
As for power it was good enough for the average load we were hauling. There were a few times on the hwy with 2 F350s on the deck and the tire lift it was a little under powered. My Driver never said torque was a problem. I'm debating going to a XL8 class 7 for my next single axle unless I go with a tandem.
Right now i want an extended cab but i'm not sure i can wait for them as I might need a second truck soon.
I also had a problem when I first bought the truck lost 4 weeks of use and 3 tows to dealer ship in the first 3 months of winter and went through 6 fuel filters. they kept telling me I was getting bad fuel or my driver was putting water in my fuel tank. after the 2nd tow I asked them to check fuel tank for leaks as there was 2 inchs of water in fuel tank, after the 3rd tow and 2 more inchs of water again, I asked if they had checked for leaks and they said they did. When I picked up the truck they said " emptied the tank, no leaks should be good, don't wash it for 3 days."
First think I thought was whats curing? so I walked around the truck and noticed a new sensor and 90 elbow on the fuel tank looked new. I took pictures said nothing. My wife (CFO) thought that was a bit under hand so sent them a invoice for lost wages. They replied they don't cover lost wages the sent me a bill for all the work as driver error. I then had words with service manager, went nowhere so i said I would take it to head office and he said go ahead.
I ended up with Western Can service manager who had already heard about issue. Then I asked him why I wasn't told that they put new parts on my fuel tank yet told me it was fine? and that I had pictures when I picked the truck up time stamped? He asked me to send them to him, 30 mins later he called and said the bill was covered. On a plus side the next time i went in ( a little scared as it is the only Hino center in our city I found out the service manager had retired.
Over all I was mostly happy with the truck just not the service so much.
