Yes,...

If so, I’d say the CMP is a copy/“inspired by” rather than having been adapted from a DUKW. It looks like somebody had a DUKW at hand and thought, “We need another vehicle like that, let’s build something much like it on this CMP we also have.”

... plus I think they used some of the more intricate fittings like the propeller drive line and ducts to construct an amphibious vehicle for fire brigade/ emergency services.

The % of DUKW components is anyone's guess, this is very much a case of "Trigger's Broom". US-based operators of DUKWs have extensively rebuilt and modified DUKWs to a stage where they are a mere "dataplate restoration/ reconstruction" like many of the warbirds flying today
