Expected Battery life when "powered down"
Sorry, no facts and figures yet, so it's tough to do the math...but...Proud new owner of a Jayco 29.5 RLS Fifth. Used it 3 weeks in May, and for 4 days this past weekend. While in the driveway after...

standby current drain can be higher than you expect. First sometimes the CO and smoke and Propane detectors are connected to +12V. Next, and worst is the stereo. The Jensen common in many units in the "off" position is really standby and draws about 0.3A. Thats 9AH/day so in 7-10days it will pretty much toast a single 12V battery. In any event, it will get the battery below the 50% level, the lowest you want a 12V to get for reasonable life in less than a week. even a pair of GC get run down in a few weeks with that load.
Completely discharging a common "dual cycle" marine battery a few times does it no good, in fact even true deep discharge really suffer cycle life when drawn below 20% of capacity. Draw even the best deep discharge down to 0%, fully dead and you do permanent damage. Very many times and they are in the scrap heap as well. Especially if it is completely discharged and then left for weeks before carefully recharging.
Do that a few times and battery may be toast. It may be worth trying for a warranty claim regardless.
In any case, if the trailer doesn't have a battery disconnect switch I'd recomend getting on and installing it and use it religiously when not using the trailer. Or, disconnect the battery positive terminal during storage.
