National Tropi Cal T370... Cat DP... what size, brand Batteries do I need... got her jumped off and home so am not in a hurry so want the most bang for the buck,

I have used Walmart batteries for years with no problems. You have a Sam's club right off I-475 that should have the good 6 volt batts. Can't say for sure, as I have not been in there.

The Built On Freightliner info for your coach says it was supplied with Two 760 CCA @ 0oF (-18oC); maintenance-free (group 31) batteries. More CCA would be even better. The originals were undoubtably Freightliner's own Alliance brand.

I've had good luck with the Alliance brand chassis batteries in my 2005 Vectra (still going strong after 10 years), so I would be inclined to replace them with the same brand. Many folks have reported very good battery prices from their Freightliner dealers.

Another thing to check out is your isolator system...

Many times I have seen older coaches with a one-way Isolator setup and the guy needed to jump start to go home.... Other coaches come with a BiRD or equal, I you are plugged in, all batteries charge.
