Had an '18 I bought new where footwell lite had to be on to run bunk heater while truck was off.
Had a bulletin from dealership about this & believe one other thing was mentioned, too. If I find it I will post.
Traded in that truck, so not sure if I still have it. -
There is a switch on dash that put power to bunk heater fan in 2021 Cascadia i driving. Switch is Slpr Htr.
Personally I think the Cascadia and and great riding unit,,driver friendly and after 47 years rowing gears the 12 speed Auto is perfect…
