Help with my new battery set up.

I have read all the posts concerning battery issues. So here is what I have come up with to power my new system.

I have purchased 6 6volt golf cart batteries from costco. They are johnson control and have 220AH. Like I said I have purchased 6 of these. I will use the six for my system and have a seperate battery for the starting battery. I will be running a onboard smart charger. I am leaning toward the pro 20 gen 2. ( open to suggestions here) Any issue trying to charge the 6-6volt batterys with this charger?

I need advice on how to wire these battries together. And How do I wire the Charger? And how does all of the run thru the perko switch?

I am very new to this forum, however, I have dug deep into the past threads and know there are some very bright people handing out very helpful information. Thank you!!!
