The 31 group are rated to deliver about 100 amp hours.
The typical small flooded cell is rated for about 60 amp hours.
The AGM will have fewer maintenance issues and is more resistant to deep discharge damage.
The cost will be about twice the small flooded cell but could return large dividends as you learn how to manage the battery system.

We used our dealer supplied batteries the first few times out.
If you only go to sites with electric hookups then they work fine.
We occasionally boondock for a few weekends a year so we ended getting a pair of 6 volt golf cart 235 amp hour lead acid batteries and they will last us thru the weekend without reaching damaging discharge levels. That includes camping in November here in NJ (temps in the low 40 degrees F). The furnace fan will give your batteries a run for their money!!
They are less expensive ($190 for the pair), have lasted us for 4 years, and are still going strong, we just keep them charged occasionally adding a bit of distilled water..
You also need to consider the type of converter installed in your RV. It would charge any lead acid battery. You will need to be sure it would work with an AGM or Lithium Ion battery, as each type has specific charging requirements.. take your time, Ask lots of questions and do your homework and everything will work out fine..
