Regarding the release latches, they will break if forced with tools. The latches are connected to the handle via relatively thin wire. What I did when I had a stuck latch was lube them blindly with penetrating lubricant and work them loose by working the handle. After getting them open enough to get the drawer rolled out I worked them some more with penetrating lube until they were completely free. That happened in 2016 and they work well now with relatively little maintenance (we drive the RT all winter for skiing so it gets more than its share of salt).
Here's a picture of the latch:
Here's a picture of the frame with striker:
Sorry for the sideways pictures, I don't see a way to fix that but I'm sure there is.
As you may imagine when the door is closed these are very hard to get to, can't be seen through the gasket. I used a straw on the penetrating lube and tried to aim for them (latches on the other doors are similar and provided a guide). I don't remember whether I could get a tool in to work the actual latch.
I do remember spending a long time doing this, maybe even left the penetrating lube on overnight.
Don't have a picture of the wire connection, IIRC I had to disassemble it to see it.
