Like essentially all current production EVs, these donors have drive units which place the motor (transversely) on are adjacent to the driven axle, so they can possibly go into other vehicles with the engine adjacent to the driven axle. That makes rear-engine vehicles and front-wheel-drive vehicles potentially reasonable targets, but not most pickup trucks. Anything with a driven beam axle at the rear would require a complete suspension replacement.Not easy because enter a Chevy Bolt in a Vanagon with a shorter wheelbase isn't easy.
But I think it could be quite ''easy'' to enter a complete drivetrain of a regular EV (Bolt, Kona, Leaf, etc) in a FWD van, a pickup or a SUV with decent wheelbase.
I think a compact pickup would be an interesting target for a whole-system swap, but it would really be a complete custom vehicle using an EV powertrain, pickup cab, and some other suspension... all on a custom frame.
