probably not, use a 110v battery charger. This may not work because the batteries sat a long time with no charge, totally dead, may have to be replaced.
Next time move the negative cable from all batteries.

Yes to the jump start. After you get the coach running, you might be able to start the generator after a few minutes. It would be best to get a stand alone battery charger and make an attempt to charge the batteries instead of trying to use te generator and on board charger. Your batteries could be toast

I'd put the jumper cables on and let it charge the starting battery for about 20 to 30 minutes before I try to start it.

Friend of mine just had the exact situation at his storage location, we let the car charge the battery and got it going.

Are they completely dead or just weak (turns over real slow)?
Also, what is the motor? A gas V10 probably. A big diesel...less likely.

If you have access to shore power, better to get a charger on it

If you do jump start, make sure the car engine is left running, so you don't kill the car battery. Also, if you get the MH engine running, operate under the assumption the battery won't restart it, so don't shut it off unless it's somewhere you can leave it.

Removing the battery terminal (or putting in a disconnect switch) is a good idea but doesn't help you now.

If you are lucky, the battery will be OK but plan on replacement.

If it's a diesel, you'll need more than a car to jump start it.

Thanks, I'm a new RVer, bought it in last october and winterized and stored, shop never told me to disconnect - pole, I guess you live and learn, batteries are 4 years old. Planned a trip to all the National Parks this July on.

Thanks, will try that first, if not have to change all the batteries, keep it AGM, as Lithium is very expensive for a retired old man.

Don't give up on your batteries. I've successfully brought mine back from near dead twice now. Since then, I keep them up with a small solar panel while in storage.
