"8 D Battery" Anyone ever use one for house batt?

Our coach came with 2 8-D chassis batteries and 2 8-D coach batteries on slide-out trays. Replaced the coach batteries seven years ago with AGM--they are doing fine, and don't corrode at all. Replaced the 13-year old chassis batteries with Sam's Club wet-cells two months ago. The 163-pound weight is not as bad as it sounds, plus the slide-out tray made the change-out easier. Harder to put the old batteries back in the bed of the truck!
