How many of us are there? Owners of Dodge based RV's?

Ok today's discovery, upon putting in a new deep cycle battery, it still does not power on its own. Shore, perfect - we had a regular fan and the fridge running today off our new cord. What should we investigate first?

I assume the engine starts. Do any of the 12v lights work when you're on shore power?

Look for circuit breakers, fuses, and switches hidden on compartments, under seats. Typically, the engine and coach batteries are somewhat separate circuits.
