My take is PEHV or even most hybrid systems are inherently more modular than a comparable ICE, lots of plug and play of known components. You effectively take out the entire transmission from the equation. A bit more complexity at the wheel with individual motors, but offsetting gearing and other mechanical items pretty well. In other words, somewhat less risky in a light duty truck.
With the hybrid F150 on the streets, a similar Ranger strikes me as a good idea. My dad has 200k on a 1999 Ranger. I tried the Chevy and Dodge smalltruck alternatives and they have nothing on Ford’s 20 year old truck.
