If it's been at the dealer for 2 months it's probably dead. My thoughts for what that's worth.....
When taking the RV to a dealer tell them to either disconnect the battery while it's there, put it on a battery tender or keep it plugged in because it kills the battery. Maybe they will do one of them, maybe they won't - but they should since not doing so is doing great harm to
your battery, they are caring for
your trailer under
your instructions.
In your current situation I figure the battery is dead. Two things can happen; tell them to have it charged when you arrive so everything works as it should OR
after ascertaining the batteries are totally dead with it sitting in their lot advise them that they have killed your batteries due to their negligence. They will tell you, "bull, we'll just charge them and you'll be good as new" (btdt). Either print the info in this link or email it to them;

Tell them to note the chart at the bottom of page 4. Compare how many charges are in a good battery never depleted vs one that has been fully (100%) discharged - huge difference. Their failure to take care of your equipment in this moment should not mean you have to pay for it down the line (after they get rid of you). New batteries.
I have done the above with success. At that time I had put new batteries in the RV but it had been a year. They replaced them when I gave them the chart and told them how I viewed it. Give it a whirl.
If you don't have success your battery won't be useless, it will have just lost about 80+% of its recharge capabilities meaning the new batteries you would have needed several years from now will just come much sooner.
