Fleet truck
I run a very small fleet and and here is my opinion:
One Peterbilt 379 with over 3.5 million KM that goes to Florida weekly. Bought used in 2002, never touched the engine.
Never been broke down in the USA for longer than 6 hours.
Always find parts required by calling dealers in our corridor, if one does not have it , the next one will. You know what parts are susceptible to wear and carry spares.
You can get a service appt. quickly ( less trucks on the road).
Pete 379 , basically same truck for last 30 years, most problems have been rectified. Dealers know truck well, can diagnose most problems over the phone.
Very easy to work on - lots of space around engine bay, where most of your maintenance will occur.
Best truck on the road!!! Why many US Owner ops buy them. Some drivers do not like the limited space.
We have a few Freightliner Columbia's with Mercedes engines. Bought new . Will never buy new again.
Trucks are pretty solid, little repairs other than engine. Lots of problems when they came out , but now mostly resolved, lots of warranty work done on engines with associated down time.
Hard to beat on fuel economy all up around 9mpg CDN. , all over 1.8 million km.
Problem : Nasty Canadian dealerships. I have caught them not changing the oil when brought in for an oil change. Only trustworthy dealer is in Cornwall, very helpful. We will not repair in MTL. will take to Cornwall.
IN the USA , TOO many trucks on the road, when you break down so have another 50 trucks. Dealerships are over taxed, you can wait 2 days just to see a mechanic. Prime, Schneider and Swift all get to go before you. Can get parts quickly but will probably bee wrong parts!!! Pretty incompetent mechanics especially at T/A affiliates.
International, still agricultural Equipment in my mind, but they do look sharp.
Volvo: Carry and electrical engineer on board to fix electrical problems , that the dealerships cannot figure out. Hard to service , engine is shoehorned in. Give truck away when finished.
Mack is good but who wants to drive one. Seems to be lots in Upper Canada, maybe good dealership.
Next purchase : Used Kenworth 660. Expecting same dealer satisfaction as with Pete. Should get good fuel mileage because of shape. Good engineering.
Secret to Success:
Good drivers that actually inspect truck and trailer and advise of issues before they become problems.
Regular maintenance , and using one gallon of LUCAS Oil additive in each oil change.
When you are small you do not want the truck to break down at all. You cannot afford to sit at dealers!!!
Mr Schneider can still survive if two of his 15,000 tractors break down. We cannot!!!
