Former Calif. fuel trucks

Company I work for has a fleet of retired CA fuel trucks. Late 90’s to mid 2000’s, all pre-regen/def engines.
Pete’s, KW’s, Freightliners.
All manual trans., all 800,000 mi plus.
All w/pto’s .
All currently have fuel tanks mounted, but will separate.
All set-up to pull a pup trailer.
As a ‘ruff ballpark estimate’, what would be a per unit value?
Owner wants sold as a group, if you want the Pete’s, & KW’s, you have take the Freightliners.
20 +/- units total.
Located in south central Texas.

 

Thats what we’re thinking, there have been a couple Mexican truck jockies that have looked, agreed to terms, then disappeared. Maintenance records can’t be found on most, so we don’t know each individual truck’s issue on why it was OOS, some over 10 yrs ago. Can’t find keys for some, no batteries in any of them.

 

Its my understanding they were originally Chevron company trucks.
The current owner, I don’t have authority to discuss.
