In the 14 years demonstrating Caravans while at Cessna, the two most common questions I recall are "what are the biggest tires we can put on it?" and "when will you put a bigger engine in it?" Don't remember ever having anyone ask about wheel pants though. The freight and passenger haulers just wanted low maintenance cost, and the owner operators wanted a go anywhere Turbine Suburban.

Their launch order is for 50 SkyCouriers.

Fedex & Cessna are mighty savvy. If there was a business case for wheel pants on the 208 and 408, they would have wheel pants.
