Just want to confirm the scale of the meter was in amps and you have a 1.7 amp draw and not milliamps. If you do then I get why the battery is drained overnight as that is a large draw.
If you have a 1+ amp draw then I would suspect that is more then just the PRDL lights. The other reason is they are feed from the headlamp switch. So we need to narrow down the possible causes from that fuse that you unplugged to get it to go away.
Do do this we need know everything that is on it including other fuses and start removing components one at a time.
I suspect if you unplug the bulb for the PRDL then it will drop some but not all the way down under 30 milliamps.
If it were me based on this info, I would unplug the headlamp switch and see what the draw does. You may have a shorted switch which is leaving the interior illumination circuit on. That would account for the 1+ amp draw.
