If it is 16 out charge soonest.
On many motor homes the house batteries are easy to access, The chassis, not so much, If this is the case put a smart charger, say 30 amps, on the HOUSE batteries for at least a few hours, then use the buton on the dash, it may say AUX-START, EMER-START or BOOST, and hold it for like 30 seconds,, Then release it for 30 seconds, hold it again and start that sucker up
Sadly I think it is too late.
It was run LAST in Oct 2013 and that was for an hr.. That would not have been long enough to even put back in the energy removed in starting it.
I would be prepared to REPLACE at least the starting batteries.
At the temps typical of Alaska I would say that the chances are that the batteries have froze and most likely has destroyed them.
I would be VERY careful about handling them physically and if you decide to attempt to charge them since very bad things can happen in the current state they are in (IE charge them OUTSIDE away from ANYTHING of value).
If the electrolyte is slushy or frozen buy new ones, do not bother charging them..
Handling them, take some heavy plastic totes/tubs (no holes in the bottom) and place the batteries in the totes to haul them home.
You want good acid resistant gloves and perhaps old clothing which you would not miss if acid gets on them.
Take some baking soda with you and sprinkle around the battery area if it looks like there has been a leak.
Until you can assess the physical condition of the batteries whether they have split/leaking or not, take caution side of things and don't assume they are not split or leaking..
You will need to assess the condition of the house batteries as they may have been drawn flat by the fridge board, propane detector, furnace board, house stereo, TV, entertainment center, TV antenna amp...
In the future, disconnect the batteries (including the house). Doing so will stop the vehicle from using up all the charge (things like the stereo, clock, and engine/drive train computer all have a small drain on a battery) and typically you can safely store your batteries for 3, possible 4 months without being overly discharged.
