Was just quoted around $1,100 for 2nd battery system, including isolator. Installed. Does this seem reasonable? Sounded like it would be about 3-4 hrs in labor for them.
So I need a deep cycle battery to run odds and ends like my cpap machine and any other smaller items I want to charge...and espar/Webasto heaters...a roof top AC unit and a mounted generator to power that. Ugh Merry Christmas to me.
