You really should not increase the size of the 12 volt breaker on the electric leveling system. Keep using a 50 amp breaker but maybe upgrade it to a better breaker like a Bussmann. The 80 amp breaker is only recommended for the hydraulic systems that use #4 strand copper wire to power the electric motor on the hydraulic pump. If the 50 amp breaker has been tripping frequently, the contacts are probably burnt which causes higher resistance and will lower voltage going to the motors.
