well maintained Electricians Truck.Dad Retired and now truck has been sitting and needs a good home.A/C pump looks bad and noticed he had been messing with something in the passenger side door panel.driven mostly between Monterey and alameda.Drove and ran great when parked and now seems like the choke is hanging up.Has some rust on front of hood and corners of cab by the hood ? I think from the dew from Monterey.Nice box with rack and Tow Receiver.Any more pics or info 510 and a 919 with 5804 text would be fastest .
