There are several ways to classify trucks, one is by weight, or size, I.e.: 1 Ton; 2 Ton; 5 Ton; 10 Ton, etc.

Another way is by the type of cab, I.e.: Day cab; cab over; conventional; etc.

And of course there is no end to the combinations of those two methods, i.e.: 1 Ton Slim Line; 5 Ton Crew Cab; 10 Ton sleeper cab; 5 Ton Day Cab;

Here are just a few examples:

CONVENTIONAL DAY CAB A conventional because this was the accepted style before cab overs were invented. A day cab because it has no sleeper. (Photo `03 Shanghai, China)	COE (CAB OVER ENGINE) SLEEPER A cab over because the cab is mounted above the motor. A sleeper because there is a bunk, or bed, behind the driver's seat. Above the stairs is the door to the JOCKEY BOX. Usually, on a COE, there is a JOCKEY BOX door, on each side of the cab. The JOCKEY BOX is one compartment under, the entire length of, the bed. (Photo `04 Burnaby, B. C. Canada) (At the studio of `Kingdom Hospital'.)	`SLIM LINE' OR `DAY CAB', COE It looks like it has a sleeper but the panels are not part of the cab. They are attached to the side of the cab to prevent wind resistance agains the front of the trailer. (Photo `05 Burnaby, B. C. Canada)
CLUB CAB Back seat compartment but no rear doors.	CAB FORWARD CREW CAB A cab forward because the drivers feet are ahead of the steering axle. A crew cab because it has back doors for easier access to the rear seat. (Photo `04 Shanghai, China)	CONVENTIONAL CREW CAB (Photo `04 Tiazhou, P.R. China
