Trekking in my view is to be living a life of moderation. This is consistent with other aspects of my life. To that end, using nature's breezes and ambience is far superior to air conditioning, etc. That's my opinion and my quest.
Our Roadtrek came with optional screens for the rear and side entry door. These are a good thing. The screen in the rear entry work well, because we don't enter or exit from those doors. I only need to unzip the screens for access to the storage below the rear king-sized bed/sofa.
However, the screen for the side entry is another issue. We enter and exit frequently via this door. I'd say it's obvious that a plastic screen with zipper won't survive long in that location. So we haven't used it.
However, to get good cross-ventilation we need a goodly sized front entry or exit point for those breezes. The side entry window includes a screen and the window pivots on a vertical hinge, and opens about 1/2 inch. This area isn't sufficient for the air movement we need. It is also a problem if the weather turns inclement.
The front of the vehicle also gets a lot of sun (infrared) load if it's pointed that way. In other words, the front of the vehicle gets hot. We really like the heat pump/air conditioner in the rear, but the front of the vehicle remains warm.
So I decided to improve the airflow. To that end I fabricated and installed a screen on the exterior of the passenger side window. With such an arrangement, we can open one of the rear doors with the screens attached and we'll get the cool breezes we love, sans insects.
This was easier than might be imagined. In fact, I'd suggest that Roadtrek offer this as an option for buyers. The screen rolls and is easily attached to the exterior with magnets. The thick black edging in the photos is not used to adhere the screen to the vehicle. Magnets at 8 points will be used.
To construct this I used aluminum screen, but it would be easy to do the same with a plastic screen. I purchased the aluminum to bug-proof the refrigerator and hot water heater ventilation. I may post on that in the future.
This is a photo of the screen, temporarily held in place with 8 pieces of electrician's tape. Magnets will be used to do this in the future. The 2 inch black edging is "duct tape" which provides a thin surface for magnetic attraction and also seals the edge of the aluminum screening. I installed the black duct tape in two layers "back to back" with the aluminum screen sandwiched between. However, about only 1 inch of the screen is sandwiched between the tape. The electric window can open and close while the screen is in place.
When not in use (when the vehicle is travelling, etc.) the screen is rolled for storage:
If I were wanting to get "fancy" I'd purchase tape which more closely matches the exterior color of the Roadtrek. I leave that for Roadtrek to offer!
Here's a photo of the screen while being constructed. If one wanted ultra-precision, I'd suggest the old trick of taping newspaper together to fit the area and then using that as a template. My parents did that to purchase a pre-cut linoleum floor back in 1955 or so. It worked then and it will work now.
After installing this, I asked G what she thought about it. She said it was a real improvement. Mission accomplished!
