Fld120 sleeper door access

Ignition key opens bunk door.
Yes lift mattress. Full access and more storage space.
Your mattress shelf hinges off back wall. The rod you see about middle of front support is the latch.

 

You drilled the door latch out. You have a hole in the door.
Put your left pinkie in the hole finger end towards rear.
You will feel a piece of metal. That needs to be pushed up with your finger.
Moves easier if you push in the door with otherhand.

 

My starter key worked in my under bunk door but had to push in on it at same time even after lube it with wd-40

 

My under bunk door is different then my ignition key. You didn't need to drill a hole through it. You could have just raised the bed and taken it apart or opened it from the inside

 

I’ve never seen one that doesn’t lift up, it’s a nice feature,on hinges, lots of storage.

 

Yes that was what the bunks did in those model trucks. Lifted up to about 55 degrees and under there you could carry so much crap. I recall in the center box we carried the main part of our water and other heavy supplies. Right side was the clean side while the left side box was what held the inverter, fluids and dirty rags etc. (Ventilation was pretty good in those days, its amazing how that big inverter did not light everything ablaze or vapors etc.

Those doors were pretty good for what they were in those days as well.
