I'd hafta say car and heres why
1) they used the same frame as the production cars ie early rancheros used the fairlane, then the falcon, then the torino
the el camino used the malibu, chevelle, and monte carlo car production
2) said vehicles used the same parts as thier car production counterparts
so IMO they are a car with a bed grafted onto the front sheet metal
