8K gen starting process

[kennyincolorado]

Good day wise RV people, I have but a simple question hoping to find an answer. Does the 8K generator start off of the House batteries or the Truck batteries? I cant find that info anywhere in my paperwork. Thanks for the help in advance.
History:
I own a 2015 Jayco Seneca 37TS(2nd owner).
I am upgrading items as we go... mattress to a Natural Latex/Memory foam etc.

House batteries were next, so I wanted to provide some more quality and sustainability to our frequent dry camping with min Onan gen operations. I went with AGM batteries as they were only about twice the cost of normal batteries, I think they well be fine for our needs....or so I think.

There are 4 batteries which provide 95AH per battery with 100CCA. Generator requires 450CCA, sort of working so far but I am wondering if I'm straining the new batteries I just purchased or should I return them for a bigger CCA. My questioned answered will determine my next move.
Again thanks

House batteries. I would have bought the same CCA as you took out, but that seems to be the one weakness with AGM. Getting like kind for a wet cell replacement.

Thx Disney, I also have the question into Jayco direct. I would have made sure the CCA was the same but the batteries I replaced were so damaged I was lucky to get date let alone the CCA. Ill post their reply
