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....
Deep Cycle batteries is what we need to be using as we will be doing a lot 50% to 90% re-charging cycles during our camping experiences... The standard Truck Start batteries are not designed for the many re-charge cycles and will start dropping off in performance right away.
Going with the two 6V golf cart batteries in series to give you the 12VDC is the way alot of members go to get high AH rated battery service.
