However, I am concerned that the finer meshed screen will adversely affect the heat transfer to the outside.
Does anyone have experience doing this?
The fridge cabinet is fairly well sealed to the inside of the camper. Bugs normally do not get past the fridge and come in through cabinet.
I would not recommend adding finer mesh screen to the top of the fridge cover. That may restrict the natural heat convection coming up and out of the fridge coils. Same goes for down at the side vent. Fine mesh can be a problem, but they do sell larger screens to fit the side vent to keep bees and larger insects out.
There are other places very small black flies etc. and get in such as;
- The 14 x 14 crack up roof vents. If you still have the original Sunline roof vents, there are small openings where the crank handle goes and between the screen and the plastic ceiling surround.
- The actual window screens. The way the screens set into the window, sometimes the screen gets shifted allowing an air gap to let insects in.
- The entry door screen door. Often the screen door does not seal tight to the door frame. The foam seal goes bad and insects can sneak around the door.
Those are the most normal ways for them to get in. What year T1950 do you have? The T1950 is a popular floor plan spanning many years and some parts of the camper did change from year to year
Hope this helps
