I bought 5 interstates all five swelled and cracked and drained all over my dads 2011 double super slide coach. Two were deep cycle under the steps into the coach ate all the paint off of the battery tray thank god for the tray. The other two were under the hood so to speak.. Same thing but ruined all plastic around them. The last one was the back up for the generator again thank god for a tray. Five batterys all withen a year old all bought at the same place same time installed buy the place they were recived from. Would only pro rate them and the deal was garbage. Well over 1300$ in batterys. I Will never run one in anything not even my lawn mower...
