Yes on the port side there is a shelf that has screws that let you remove the face, you will have to remove the mattress to get at the screws at the floor of the cave, then you will have access to where you can run the hoses and electrical for the heater.
I do not know if the face of the stairs can be removed, but the heater and air inlet grill is mounted from the cabin side , not the inside of the step.
