Older Keystone units had too small of breaker. That hydraulic Pump can actually draw up to 80 amps or so under load. The fix Keystone did for Montana owners with that problem was to add a second breaker in parallel. We started to have problems with our Previous Montana and did the breaker up grade and never had another problem.
