Hello all, I am a new owner of a 1999 30' Airstream Excella and new as a member to this site. I was able to use my camper a couple of times before the end of the season, I know,I know, it's always camping season. Anyway I have performed repairs on several small things, mostly maintenance items that were not performed by the previous owner. Now I do have some questions about the battery charger, I have pulled the batteries out of the camper and have them on a battery tender for the winter but wonder if it is safe for me to have A/C power to the trailer while there are no batteries installed. I like to check on things from time to time and like to be able to have lights. The other question I have has to do with my couch that converts to a bed, there is a storage drawer beneath and the slide hardware has failed and ballbearings are everywhere. Can this hardware be fixed or do I need to consider replacing it. Please advise....
