Hi Mark. Welcome to the Forum.
Removing the innards from an Airstream is relativly simple. The ovens usually have 4 to 6 screws holding the top and front to the cabinet face frame. Don't forget the gas line. The're on the rear.
The fridge also has a few screws holding it to the cabinet. The more difficult ones may be on a filler piece between the fridge and counter top. There are also (at least on mine) 2 half inch bolts with nuts holding the fridge frame to the floor. They were so rusted that they needed to have the nuts ground off. Gas line is towards the front.
The cabinet just has 1 or 2 screws into the floor and a couple into the wall.
70% of the cabinetry on mine has been replaced or restored and getting the pieces in and out are the easy part.
Good luck with your project,
