Chase card conditions say: the high value vehicle exclusion does *not* include pick-up trucks:
(in other words they DO cover them)
what you quote is the regular info landing page - go to the full benefit details PDF for more specific info:

"Certain vehicles are not covered by this benefit, including: high
value motor vehicles, exotic and antique cars (cars over twenty (20)
years old or that have not been manufactured for ten (10) years
or more), cargo vans, vehicles with open cargo beds, trucks, (*other
than pick-ups)*, motorcycles, mopeds, motorbikes...

(my asterisks)
But that's a good idea - to call and confirm.
thanks!
