Just some info that may help someone. Lippert changed my level up to 6 point from original 4 point 2 years ago,did a good job. They had to change pump and they installed an 80a manual reset. The 80 would trip in low temperature,below freezing,when using auto retract but not with any other operations.Checking voltage it would drop below 12v under heavy load. Factory wiring on mine was #6cu about 25' of wire.I moved breaker closer to battery and replaced wire with #2cu.About 18' of wire now. Voltage drop now is about .3 volts at motor under load. This morning,27 degrees, breaker did not trip in auto retract but rear jacks did not fully retract. I am assuming pump sensed enough pressure it sensed jacks were fully retracted.They retracted fine in manual mode.
