RENTON, Wash. -One of the highlights of Kenworth’s EPA2010 truck lineup is what it claims to be the industry’s only completely clear back-of-cab (BOC) -both above and below the frame rail.

Samantha Parlier, vocational product marketing manager with Kenworth, showed off this accomplishment during a recent visit to Kenworth headquarters. The great enabler is an aptly-named, 6.5-gallon Clear Back of Cab DEF Tank which sits cleverly tucked over top the fuel tank.

“Kenworth is the only OEM that allows you to run SCR with a completely clear back of cab both above and below the frame rails,” Parlier said. “We can package the batteries, fuel tank, DEF tank and the exhaust system underneath the cab and that little 5.6-gallon tank is the reason we can do that.”

That engineering achievement is likely to be popular with vocational truck body builders. Another treat for body builders is they can relocate all the tanks and pumps found on a Kenworth truck to accommodate their own requirements.

The completely clear BOC was showcased on a Kenworth T800 extended cab dump truck, although the extended cab isn’t necessary to achieve the clear BOC, Parlier said.
