I decided to look at the basics and sure enough both house batteries were bone dry on water. I didn't realize the SN charging system was always on and doesn't turn off when the batteries are fully charged. At least that's what I read on here somewhere. I'm assuming this would cause the batteries to need water added more often the my old coach. I only had to check them at the beginning of the season. With any luck the batteries will come back to life. They look to be fairly new Interstate brand but the install date codes stickers were not pulled out so no real way of knowing how old they are.
