This study and document was completed

by a third party company and is intended

for the exclusive use of Western Star dealer

personnel. The information and conclusions

contained in this booklet relating to competitive

products are believed to be accurate at the

time of analysis and publication, but do not

necessarily apply to other similar competitive

vehicles containing different specifications

and/or later dates of manufacture. While

every effort was made to provide accurate

and realistic comparisons, differently specified

vehicles or vehicles manufactured subsequent

to publication could yield different results.
