I dont realy know what I dont know. any advice would be helpful.

What does the charge specs on your batteries owners manual say for absorption and float? If you don’t have it what is the make and part# of the battery?

This is what my Trojan’s batterie settings are:

Absorption 14.7
Float 13.5
Eqalize: 16.2

Yours are likely close. You may need to add distilled water and equalize the batteries.

Not the best idea to add a new battery to an old one. Kills the new one quicker, but “It is what it is..”

Battery is an everstart deep cycle 29DC 845 Cranking amp, I dont have the manual

Everstart is a WalMart. I honestly don’t know if the Trojan Charge Profile will work.

There’s something called batteryuniversity.com that may cover charge profiles more.

I'd say with a single marine battery, don't overthink it and go with 14.4V absorption. Most of your loads do indeed seem small, but if "small fridge" is running off electric then that is a bigger deal than you may realize. If it is a propane fridge, use propane while boondocking. I recommend switching over to 2x 6V true deep cycle golf cart (GC) batteries rather than adding another 12V, there is a good reason why this is a standard setup among boondockers. Costco is a good source for reasonably priced and available 6V GC batteries.
