Just bought my first Dolphin. A '92 900 moldel with 77k. The refrigerator isn't working on either 110v or propane and I'm going to look into that but meanwhile I'm wondering if anyone has gone completely away from these in favor of more modern low-e refers running off the battery? I have a friend who did this (not in the context of an RV, think solar powered kegerator). Any thoughts or advice would be welcomed.
