My 21 foot TT came with a small deep cycle battery. My Problem is when I dry camp it doesn't last the night running my cpap machine. Cpap has a real low draw. I am going to install a 2 battery system....
I wouldn't know why you wouldn't buy deep cycle batteries. If you think you are going to get more longevity from starting batteries for your money, you're not.
If you take even a little care of your deep cycle batts, like keep them clean, watered and fully charged as possible on a 3 stage converter charger, they will last.....like forever.
