Two answers. First it is a 2019 so the 2nd answer DOES NOT APPLY.
Modern RV's have converters with good voltage control You can leave 'em plugged in 24x7 for years and not damage the battery (Mine are plugged in all the time save when on the road (Then I boondock overnight) and lasted 9 years. the new batteries lasted 4 years before I had to add water And of course are still in there and for the last few days they both recorded some overnight TV and let me watch an hour or so a day (I got a bunch of catching up to do TV wise :) )
Tonight i'm on shore power. (And tired. 800 miles plus in under 4 days)
The other answer (STOP READING NOW IF YOU HAVE A NEW RV)
Some older unts had a long since discontinued battery killer of a converter . but anyting made this century won't have it cause it has not been made in more than 15 years.
