Just something that I would like to share. I have a B+ 225 and I really hate to run the Air –Conditioning in the early or late summer months. I tried unsuccessfully to find a screening system for the front Van doors. Here is what I came up with.
Get some fiberglass screening and 2 ft roll of self stick Velcro. I used white because my Van is white. Cut 8, 1 inch pieces of Velcro for each door . Open your front doors of the van and cut the screen to the same shape as the window leaving about a 3 inch border.
On the door itself place the I inch hook side of the Velcro equally spaced to the border of the window door frame, outside of the edge where the rubber door seal hits the door. Now hold up the screen to the window and match up where you have to attach the mating side of the Velcro to the screen. I attached the Velcro onto the screen itself by overlapping the Velcro to itself on the edge and using a staple to hold it closed. Now attach the screen to the door on the door, it looks like a loose fit but when you close the Van door the rubber seal creates a seal. You can still open and close the window as much or as little as you want. They are easily removed in only a few moments and take up no space to store ( just fold ) and very cheep to replace if lost . If you need further information just let me know.
