You're in VT, so presumably serviced in the fall meant winterizing months ago.
And now the dealer is going to keep it through the winter??
So like 6 months to blow out the water lines and fix whatever they crunched?
They're playing you for a sucker.
If you don't have the fortitude to demand being made whole, in a timely manner, then let your insurance co deal with it.
Actually, make sure your insurance co deals with it, as they have a better chance at getting it fixed right. And they will have no problem going after the dealer or their insurance to get their money back.
Good luck with the outcome.
