They were 24's and luckily an autoparts in Kirtland (the one near farmington that I'm spelling wrong...that kirtland) had the exact ones, had posts and bolt both just like I removed.
My worry about the exact battery type was solely cable reach. Bigger than 24 would have been great, but these are temporary and will be changed out within a month.
Direct easy replacement except for:
I loosened all the nuts(1/2"socket) but didn't take them off.
I climbed under the coach to get the clips on the holding straps off.
And while I'm under there, My dad decided to help, so he pulled all the cables off.
Luckily I had pictures to match it all back up by doing forensic exams on small scratches on the lugs and tape. That's a 350amp fuse on that 4/0 wire. I was a bit skeered, but got it all correct the first time.
All seems well.
Because of the way they wired up the new inverter, the roof ac wouldn't power because (I think) since the fan wasn't seeing 12v the compressor wouldn't come on...even when running the generator or shore power. Chassis power made it work for a while, but batteries got so bad so quickly that even that failed to let the compressor kick on. It was 105° in the rv before I got it all running. It's cooling down now. Dash air had little effect on the entire coach.
I have gone from thoroughly convinced I knew what was up, to thoroughly confused as to why a damn bad battery screwed me so bad when I have a converter.
Punchline:
I now have two new 24's that will allow me to not have to rush the six 6volt batteries swap.
$178 out the door.
Thanks for info. It had great value to me.
