So, final verdict is to dump the batteries, get new ones, laugh, and move on. Okay. I think the money is, at this point, worth the headache of continuing to try and sort out these batteries (with one missing two sections of two terminals).

Thanks all!

No, the final verdict is slow down, figure out where you're at, sift through the BS and the good info and then move forward.
The way I read your posts is like you gotta leave x country tomorrow morning and can't stop or ever come back, lol.
First, are you aware your camper has a battery charger in it? Plug the camper in, batteries charge or stay charged. There's about a .01% chance I'm wrong about this, and I'm sure some rvnet expert will tell me it is physically possible to buy a camper without a battery charger, but please dont. Campers have battery chargers.

Second, did you really arc off half the battery posts or is that an exaggeration? It does not seem like there would be that big of a DC current draw when hooking your batteries back up. If it really did weld/melt stuff, was the fridge/heater fan, bunch of DC stuff "on" when you hooked them up? It shouldn't spark like that, even hooking up positive last.
3rd, how do you know you need new batteries? Have you tried to fully charge them? (Remember 2 days ago, they were froze solid like bricks....but they weren't apparently)
Do they hold a charge? They should be sitting at 12.5-12.6 volts a few days after charging, with NO draw on them.

This is not a big deal. Worst case you killed a couple batteries by leaving them set out for a couple months in the winter, not being charged.
Brand/type? Go buy some batteries (if you need them), deep cycle, any flavor and go camping for a few years and then figure out if you want to become master camper electrician battery goooroo.
