* Wheelbase: P-30s came in various wheelbases, affecting overall length and thus weight.
* Engine: Different engines added or subtracted weight.
* Options: The presence of air conditioning, power steering, additional axles, body type (the specific step van configuration from the upfitter), and other options all impacted the weight.
To find the curb weight of a *specific* 1974 Chevy P-30 step van, you would need to find its original specifications (if documented) or weigh the vehicle itself. The GVWR would be found on a sticker typically located inside the driver's side doorjamb or on the vehicle's data plate. The curb weight will always be less than the GVWR.
