We have the same year and model Alpine and we do not dry camp. I suspect you are probably going to be due for a new battery. The Interstate battery lasted a little over 2 years. I bought a replacement at Wal-Mart (their brand) and after about a year and a half it would not hold a charge. Wal-Mart checked it, then replaced it with a new one, no questions asked and no pro-ration. Note however that although the replacement battery was brand new, I was not given a new warranty. The warranty is due to expire on the same day as the original battery I purchased from them. In other RV's I've owned the battery seems to last 2-3 years.
