Thinking about changing my 3 year old battery before the season starts should you buy a deep cycle battery like boats use since it is recharged all the time or any good battery ok?
I've used dual Group 27 or Group 31 deep cycle batteries for years (depending on the rig). Costco is a good source for decent Group 27 deep cycle batteries. I have two of them fitted in my Pleasure-Way Traverse Class B.
