Just saw the other day that Cat is introducing a new vocational truck at ConExpo coming up next week. I'd guess it's Cat powered? They had a teaser vid that I saw of a tandem dump rig.
On edit here's some info...
Unveiling of First Cat® Vocational Truck at CONEXPO in March 2011
PEORIA, Ill. – Caterpillar Inc. (NYSE: CAT) will unveil the first model in its
full line of Cat® Vocational Trucks, the Cat CT660, at CONEXPO on March 22, 2011.
The Class 8 trucks will be sold and serviced exclusively through the Cat North American
Dealer network, with production beginning after CONEXPO for customer delivery later
in the year.
To develop its first line of trucks, Caterpillar leveraged its industry-leading
technologies, extensive knowledge of worksite and operator environments gained from
meeting the heavy equipment needs of a wide range of industries, and an unparalleled
dedication to customer support. The trucks will offer custom solutions for a large variety
of job applications—from moving rock and hauling trash to logging and pouring
concrete.
Before Caterpillar engineers started designing, the company asked vocational
truck owners and drivers what they wanted and needed from their trucks. “Our design
and manufacturing has been focused squarely on making the customer input we gathered
a reality,” said George Taylor, Director and General Manager of the Cat Global On-
Highway Department.
Taylor added, “We coupled customer input with our knowledge learned from
years of experience working closely with different industries to meet their heavy
equipment needs to identify the ideal standard options for various industry applications.
As a result, we’re proud we will deliver a line of vocational trucks that our customers
want, knowing they are built for a wide variety of jobs.”
Caterpillar will offer the heavy-duty Cat Vocational Day Cab Trucks with a full
range of popular engine ratings and torque capability options. The specs are designed
explicitly for customers' demanding applications and include a Cat CT11 engine with
ratings from 330bhp to 390 bhp, a Cat CT13 with ratings from 410 bhp to 475 bhp and,
coming in 2012, a Cat CT15 with ratings from 435 bhp to 550 bhp.
Because of its proven record for quality and reliability that maximizes uptime, the
Cat CX31 torque converter style automatic transmission, with three standard locations for
Rear Power Take Off drive positions, will be a noteworthy option for Cat Vocational
Trucks. Caterpillar also offers a complete line of other OEM vocational transmission
options, including Eaton manual and automated manual transmissions.
“These trucks are everything the Cat brand represents in terms of quality,
durability, reliability, and driver ergonomics, so we’re looking forward to seeing the
reaction to the CT660 at CONEXPO,” said Cat Vocational Truck Product Manager Gary
Blood, who is responsible for product strategy, design and introduction of the new trucks.
