The first thing I would do is get a portable battery charger, and try charing the RV battery. If you leave a battery discharged for any lenght of time, it will not fully recover, and will suffer perminate loss of capacity.
If you do have a short in the wiring, you will need to disconnect the battery from the RV to recharge it.
Now why did the battery discharge all the way?
If you have the RV stored, and did not disconnect the battery, then you ight have run down the battery from such small loads as the 0.5 amp propane and CO detectors, over a few days will dischage a battery completely.
However if you left the RV plugged in, then it should have stayed fully charged. many people like the prices here. www.bestconverter.com
I don't think I would use the same brand that failed you this time.
You can determine if you have a short in your wiring by hooking up a 10 amp battery charger. If the meter reads 10 amps for a while, then slowly goes down to about 8 amps, then it is charging the battery, and all is normal. But if it keeps reading 10 - 12 amps, you probably have a short circuit, and it might exceed the ability of the charger to overcome that short as well as charge your battery, so disconnect the - line, and put the charger only on the battery.
Of course if you are running 2 or 4 lights inside the RV at 1.1 amps each, that will present more load than the 10 amp charger can overcome. And it should take a 10 amp charger about 10 hours to get a 105 amp hour group 27 battery full, double that time if you have 2 batteries.
Ressit the temptation to put the charger on the "Start" mode. It will overheat the charger, and it probably states in the instructions that the start mode is for a maximum of 20 seconds, followed by 10 minutes of the charger unplugged to allow it to cool off.
