I appreciate the opinions, knowledge and experience of the forum members here. We all mean well, based on our experiences, but I was told on this forum to buy a wet, deep cycle battery and since my trip to Alaska and back, I can say, from my experience that an AGM battery is better. It lasts longer, where my wet, deep cell only made it half way through the night. I contacted the manufacturer of our power converters and they recommended an AGM, as long as it meets the charging requirements of the charger. I now have an AGM deep cell battery and it functions through the night and into the morning.
