Switching from dual purpose to deep cycle: advice?.

[Byrd2001]

Appears ‘learning battery’ is dead after left outside on TT during frigid cold waiting for repair parts. Current battery is InterstateHD24-DP. Considering deep cycle, but wonder if I need to consider switching any other parts of electrical system at same time. Currently occasional boondocker. Mostly use shore power.
(Never thought to pull battery before dropping off...but learned a lesson...so I'm chocking this up as a learning moment)

It would help to know your charging sources now. Learner battery, been there, done that.

If you have room for 6 volt golf car batteries Exides ARE deep cycle, you need 2 & hood the pos to the neg to make 12 volts. Here's a link to them for size & info https://www.ruralking.com/exide-golf-cart-battery-6volt-gc115g

Current battery box sits on tongue: 9” tall, 8” wide, 11.5” long. Current battery just fits in this box. I could go a little longer if needed.  Prior to repair mess-up, I kept in garage when not camping and plugged into 120 about every 2 weeks. I knew was charged as I have a small digital display on side of battery box. I’m OK with a direct replacement if that appears best option. But I much prefer insights and suggestions from this forum before entering a store. Thanks

Also charge from alternator when in tow! Sorry...I assumed that was standard, but I found it is not always the case.
