I am not a fan of the Interstate Marine batteries that come with our trailers. They are fine to power your emergency breakaway switch but if you are doing any dry camping they are inadequate. If you are going to need the extra Amp Hours for dry camping, you may wish to sell your brand new Interstate for whatever you can get for it and get a couple of 6v true deep cycle golf cart batteries (Costco in Canada usually sells them) which will give you considerably more jolt for your buck.
