AGM and Wet Cell in parallel

Thanks to all. The AGM will be installed inside a truck camper where it is hard to maintain a wet cell battery. The conventional deep cycle will be outside in front of the wheel well in the truck bed. I plan to use a quick disconnect to facilitate unloading/loading the truck camper. The AGM alone will be used when the camper is unloaded and hooked to shore power. The combination will be connected when boondocking with the camper on the truck.
