• UsageS— ome of the idle reduction
units experienced operational
issues which either limited their
effectiveness or resulted in the
units being inoperable for a period
of time. The payback periods for
these units were extended due to
the 1) diminished fuel savings during
periods of inoperability, 2) additional
time needed to compensate for
these periods of inoperability and
3) added costs associated with
downtime, repair and maintenance.

• CostsB— eyond differences in the
purchase and installation price of the
various idle reduction technologies,
annual maintenance costs and the
potential for recapturing a portion of
the purchase price upon the sale of
a truck are two factors that are less
understood. Determining the period
of benefi ts (year-round or seasonal)
and the price of diesel fuel are also
important considerations when
determining the payback period.
During these demonstrations, the
average price of diesel ranged from
$2.69 to $3.15 per gallon. The
average price soared to a high of
$4.76 per gallon the week of July
