O.K., I have a the same style remote thermometer and it sits on my deck. When the sun hits it directly, it will measure many more degrees than the actual air temperature. Today it measured 117 degrees when the actual air temperature was 72. I think your thermometer got hot from direct radiation from the sun, not because the air in there got that hot. To test this, put the same thermometer on the OUTSIDE of the plexi and see what it measures on the same sort of weather day you did your test under the dome.
Think about it; If you didn't slide the shade cover over, and let the sunshine in, the inside of the camper would get hot. Very hot. Not because hot air, but because the solar radiation heats the object it's shining on. That object then heats the air in the camper.
Another example; I can put a thermometer in my living room with the AC on set for 75. If the sun shines in the window and shines on the thermometer, it will register a much higher temperature because the thermometer itself gets hot, not the air around it that it's supposed to be measuring.
The only thing that got hot was your thermometer, not the air around it.
