Battery replacement

Absorbed Glass Mat (AGM) batteries are very good as long as you don't discharge them below 10V. Most automatic chargers will not recover an AGM below 10 volts. The way to recover them is to fool the charger by hooking a good normal battery in parallel with the dead AGM for a short amount of time until the AGM gets above 10.5V. Here is a link for recovering dead AGM batteries.

x2. I've revived many AGM motorcycle batteries using this method.

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.

If you always camp with hookups any battery (even a lawn tractor one) will do.
For dry camping I'd upgrade to a G29 or G31-size for the small increase in cost.

I have 2 group 31 Sears Platinum Marine (made by Oddysesy) AGM batteries on my TT. I can go about 10 days before I need to charge them.

Definitely get a Marine Deep Cycle Battery like the ones here:


Marine deep cycle batts

No matter where you buy it Marine batteries will be sized by "Group" number get the highest Group number you can fit. A group 31 would do well and last a long time. The higher the group number (in the Auto sized type batts) the more reserve power the battery will have.

You can get decent Marine Batteries at almost any big auto store like NAPA. Or Sears.

pick up a battery that says deep cycle marine. NOT deep cycle starting. we use interstate batteries .

It depends on how you use your rig. If you always have an electric hook up any battery will do. If you spend any time dry camping you want a deep cycle and the bigger the better.

deep cycle is the way to go

Generally the batts you get at auto parts stores advertised as "marine" are combination cranking/deepcycle. They're okay for most applications (I have two each in my FW and boat), but they're not, for example, like golf cart batts. They should suffice unless you go off the grid for days at a time.
