Would anyone have an actual Dutchmen 7pin harness to trailer wiring diagram or know which wire colors match up in the junction box?

A google search should show a picture of pin assignments.
Was the tow vehicle connected when you measured the 2 to 3 amp power drain? If not, it may not be the problem. Only two pins would affect your issue: the ground center pin and the 12 volt supply pin. The 12 volt pin is upper right when facing the plug end. Don't trust my memory, put a meter on the tow vehicle socket and find it. All the other pins in the plug should be dead when plug is disconnected. They operate exterior signal lights.
My 1000 watt inverter draws 2 amps when idling. Maybe you have an inverter wired directly to the battery circuit some where.
The only other device that draws in that current range is my furnace. Do you have a 12 volt refrigerator?
