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?
If the trailer is at home and you have access to shore power, why did you take the batteries out? I have never once in 30 years taken batteries out of my RVs. I also leave mine plugged in 24/7, check the batteries monthly. Never had any issues.
