I want to add a power lift gate on my caravan that I can open with the remote key....Can it be done? Cost?

 

It will run you around $500-1000 for all the parts and equipment and require about 4 hours or more work. It is a lengthy process requiring swapping out the left D pillar trim panel and the liftgate inner window trim panel. You have to add the motor and armature and the wiring if the van does not have it tucked away behind the D pillar trim panel.
