Super simple modification: Screen door!

EASY bug solution for those who like to have the door open!  Got the idea from friends who sail - they used this for easy in/out to the cabin of their catamaran.  Magnetic closure.  This is the one I purchased years ago for my own porch door, it's no longer available but there are updated versions:  https://www.amazon.com/gp/product/B01H3X7FFE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The Barefoot has a little lip above the door which makes it amenable to simple clips.  You can find edges on the underside of the trailer, left and right of the door, to use for affixing the bottom of the screen to create a bugproof seal.  I used these:

Fold up small for easy storage in one of the overheads: 

In action: (note that it does close completely when the bottom clips are in the right location, this was a "quick and dirty" installation for the purposes of this post)
