need new deep cycle batteries for class a

We just bought our 4 marine deep cycle batteries of the proper class/type at Wal*Mart for a good price. Sam's Club also carries these types of batteries, as do many places...shop around for the warranty and size you need. Some stores will also install them but be sure to draw out or take a photo of the hook-up diagram before you take out the old ones. One Sam's Club would install them and one would not...make sure you find someone that is willing to prep the area well and has experience with multiple battery installation. We did it all ourself this time, took photos be be sure we got the connections right.
