You do not have a hydraulic leveling system and that is the system that would be able to use the 80 amp breaker upgrade. I would advise using a new breaker the same rating as what is already installed in the rig, because the wiring for the electric leveling system is no way large enough for the 80 amp breaker, and if there was an electrical short or other failure, you will likely start a fire because the 80 amp breaker would not open up soon enough.
