....I am getting one more battery box and getting 2 GC2 6 volt batteries, also at costco for about the same money. They are true deep cycles and are made to be discharged further without damage. With new cables and boxes it will be about $225 for way more than double capacity. Should allow me to run anything I need overnight without worry that I will wake up cold.
Good assessment of your battery use and the 6V's. I have a pair of Sam's Club 6V's in my trailer that are 5+ yrs old. They don't get abused, often. Today might be a good day to check them and see how they're aging but I'll bet that they go at least 10 years. I have them charging with solar every day.
