I think it boils down to this, (for the class 7 and under crowd)
Freightliner , most truck for the least money, large dealer network with many open 24hrs, parts are cheap, it's really not a bad truck, have a choice of engines
International, no choice of engine (International only), they have had issues with it as well as the electrical system on the new style cab, alot of their dealers have lousy hours, truck is not as low priced as it used to be.
Hino, people are starting to figure out these units are not meant for high mileage highway service, yes some do Ok but those folks are lucky. Lack of dealers and engine issues being the other downfalls. Truck is very low priced though!
KW and Pete, great truck, nice cab, small dealer network, parts are more money, price of the truck is too high.
While there are exceptions to every situation, basically the Freightliner gives you the best value for your dollar and should be the least grief to own.
But truck buying and owning is a personal thing, you will run into boosters and haters for every brand, armed with stories to prove their point!!
