Depending on how long it's been dead and how low it is sitting at the battery can easily be totally ruined.
It would take less than a few weeks at less than 10v for it to be unable to be salvaged. And, if you do get it charged back up it will not hold that charge as long as previously and the number of use/charge cycles left in the battery could be very low.
Since your RV is a 2013 if the Chassis battery is original it might be best to just go ahead and replace it.
One more thing... have you tried the Aux Battery switch on the dash to start the RV with help from your house batteries? Or are they dead too?
