Battery draining question
I'm pretty new to RVing. We have been inveterate tent campers, but last fall purchased a used '07 (or '05 - somewhere around there) hybrid travel trailer (Jayco JayFeather 19-H) so I'm pretty new to ...

Some information: First Marine/Deep cycle batteries are starting batteries (marine) First and only lip service to deep cycle... GOLF CAR batteries are DEEP CYCLE from the drawing board to the delivery and install.

your 130 amp hours gives you around 50 usable amp hours.. A pair of six volt golf car batteries will more than double that (230 amp hours and you can use half or 115 before serious damage sets in).
They also recover from OH-@@@@ discharges better, though you should still avoid those.
Finally it takes several hours to properly charge batteries... The proper max charge rate for MOST batteries (LIfeline AGM is an exception) is 30 percent, so for a pair of GC-2 Golf car (230 amp hours) that would be 69 (Call it 70) amps.
At this rate if you take the battery to half full (130 amp hours) it will take about 2 hours to bring it back up to 90 percent, and 2-4 more to finish the charge using a 70 amp 3-stage converter (not your tow vehicle)
NOTE: You get nearly the same performance if you double up on what you have battery wise... Due to the differences between Marine/Deep cycle and true Deep/cycle the numbers come out nearly identical Just the lowest state of charge is higher.
