Not sure if this is just a temperature issue but our Sierra has four slides and not all the time but randomly the forth slide will stop coming in. We wait 5 seconds then it will restart. It sounds like something trips near the resevoir. If is was a temperature issure I would suspect none of the others would come in? Or not? Sometimes it can take 4 tries to retract sometimes just 1. If its due to cold temperatures I can live with that and upgrade the oil. Always the same slide. Any help or advice would be greatly appreciated by us two Aussies.
