Adding another 12 volt battery
My fifth wheeler came with one battery but when we lose power it does not last long for the 12 volt lighting. What harm would I be doing if I added another battery and ran it in series with the other ...

OP,
Keep in mind that if your current battery is older, and it sounds like it might be based upon non-specific time of "does not last long", you would be better off replacing the current battery and maybe considering adding a second battery. Do not just add a fresh, new battery in parallel to an old, failing battery as it will negatively impact the new battery. Likewise, both batteries should really be identical, including length of service, for maximum usage of both batteries.
