2013 3150RL with the same problems with slide out and jacks - the breaker trips repeatedly and gets worse as temp goes down or if not plugged into shore. Obviously a voltage drop problem that causes the amps to go up on an undersized breaker. Hitting the breaker over and over will weaken it over time and make the problem worse. I finally got an amp gauge installed and see 70-75 amps when not on shore power with new, fully charged batteries. As soon as the voltage drops to 12.2 the amps go to 70+ and the breaker trips. As my storage area has no power available, it was getting to be a real pain to get the jacks retracted to leave on a cool morning.
My research on wire sizing shows the cables OK for that amperage, particularly for short durations. So, an 80 amp breaker is on order and I will post again after install and I get some more readings. Thanks again to this forum for great info and sources of supply. Consider those comments on lack of design/engineering/customer hassle made again and I'm sure Keystone saved a few bucks on a circuit breaker.
