Fleetwood — D-body (1993–1996)

1993–1996 Single-source

Wikipedia's Cadillac Fleetwood article names RPO V4P as the factory towing package, dates it 1993 and says it was revised 1994–1996 with the LT1 engine; the same article says the package was shared with the Buick Roadmaster wagon; the contents it lists are package contents and date no year, so none is a row here

This page aggregates every documented appearance of V4P in the Cadillac reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
