Correct Auto (Chassis) Battery for 345LE

Dear 1989 345LE Owners,
What Auto / Chassis Battery do you have installed?
I am trying to figure out what the recommended battery specs are but I can't seem to find any info in the manual or where to look on the internet besides bothering this wonderful community for advice.

I can't think of all the relevant specs but for instance, my current battery's CCA is 775 / 55Ah
Could my current battery possibly be under spec'd?

If anyone would be so kind as to post what brand/model of battery they have installed and treating them well, I would sincerely appreciate; or any advice would be welcomed, thanks!

I have an Interstate for my starting battery; which I bought the largest that would fit, (which I wouldn't know if it would fit in your coach) and the highest cold cranking amps, (1000 CKA). You can't go wrong going big, especially since mine has to crank over a 1150 lb diesel engine.
