Well I already have one 12 gallon Moeler tank from when I had my pontoon to go in the boat, and in thinking on another.

With the dual batteries, and full tanks that's a lot of weight to the aft, so I'm thinking on placing the batteries up front. Longer cables but whatever.
Should I tie the tanks together and draw from both at the same time for even weight distribution or use them separately?

There are great deals on long battery cables on eBay.

I would say draw from both but make sure they are both empty, or treated
with Stabil, at the end of the season or you will have bad gas in two
tanks. Will you be able to easily see how much fuel you have?
