It really isn't hard to remove and you don't need a hammer! Turn off the propane at the bottle. Remove the propane connection at the bottom of the fridge, then open the top of the stove and remove the stove top propane connection. Unscrew four screws that hold down the stove top to the fridge located inside the stovetop. The stovetop lifts up and out. My
1961 had a vent pipe to unscrew but I don't know if the 63 has one. The hardest part is unscrewing the four bolts that hold the fridge down at the "feet" of the fridge. Once they are removed you can slide it out inside the trailer.
