Well I have to correct some information I put in a previous post, After arriving in Arizona and finding night time temps to be colder then expected I find my 3 batteries can not keep up to the furnace load at night just to maintain 65* temps inside the trailer. Even with the freezer unplugged from 12V power, running the generator to 10PM I find my batteries are at 11.4V at 6AM in the morning. Needless to say, I am destroying the FLA batteries in short order. Bit the bullet and bought a 270amp Lithium battery and a 30amp Lithium charger to replace factory charger. Before the need to run the furnace at night my 3 Interstate batteries did a great job but cold weather is just too much load for them.
