provides full engine-off heating capabil-
ity. The system is designed to eliminate
the need to idle the engine to run the

Powered by four dedicated Paccar
batteries, the AC system has a
small under-bunk footprint to main-

“Once the truck is turned off, the
driver simply uses the control panel in
the sleeper to maintain the temperature — there are three fan speeds for
airflow,” VanVoorhis said. “An LCD
display gives drivers full system information, plus allows the driver to monitor remaining battery power.”
Once the truck is back on the
road, the batteries are recharged to
90% capacity in 4. 5 hours, the company said.

A Cabover Makeover For Kenworth
Kenworth has made several updates to its Class 6 K270 and Class 7 K370 cabover
trucks designed for city and neighborhood applications.
Changes include a new dash and
gauge cluster, front air-disc brakes,
electronic braking module, and an
updated exterior. The Kenworth K270
Class 6 and K370 Class 7 cabovers
are targeted for applications where
a tight turning radius and a shorter
overall length are required.
The company said that more cities are starting to restrict the overall
length of trucks or are allowing broader
operating hours for short overall length
trucks and Kenworth expects those
trends to continue, which likely will
drive the movement toward cabovers.
Inside the cab, a new dash and
gauge cluster provide more information to the driver than ever. Both
trucks incorporate a standard air ride
