Drain tubes--you have to pull the refer to replace them, except for the freezer, which is already at the bottom rear. I asked if the cooling unit had ever been replaced.

Last, IF you never OPEN the interior doors in transit and the temps rise, that points to the refer PULLING in outside air. A CLOSED refer, even if NOT on, will not have a fast rise in temps as long as the doors are not opened. I bet you have a partially blocked cooling unit, which when you are in the temps you are in, is the symptom of a partially blocked cooling unit.
