And sometimes easier. Go to Autozone (or similar), you'll find ready-made pos. and neg. cables in a set. They're meant to wire starters. That's what I used.
I also strongly advise getting a battery minder Batteryminders Specials | BatteryMinders.com
I remove my batteries when I park the trailer and get them out of the heat (or cold) and keep them on a maintainer. Don't depend on your on-board converter to maintain your batteries over perods of non-use, especially if, as you said, you don't go very often.
So, two, identical, brand-new, deep cycle 12V batteries, wired parallel is what I use. They're sitting in my basement on the Battery Minder and will be until July 4 when they go to a cow pasture along the Shenendoah River for 4 days. Then home and back to the basement.
