I have winterized my 5th wheel and removed the batteries. I need to open the slides. Can I hook up shore power and open the slides or do I need to reinstall the batteries?
I was at a dealer and wanted to see the slide out on a coach they had. No batteries in the unit. They went and grabbed one of those little $50 Harbor Freight battery jump boxes. It pushed out both slides and powered all the auto-leveling jacks. Pretty impressive for what it is and the cost. I plan to buy one for backup, so to speak.
