Chevrolet Holiday C10
An old pickup truck with an equally old camper make for an almost cliché scene in a back lane.
This is Cheverolet Holiday C10 (or possibly a K10). According to originalelmo, the lower bowtie/10 logo indicates that it is a 1966 model. As dyintryin90 indicates below, the "Holiday" logo probably refers to a name used for the truck/camper sold together.
