We went to a (tent) camping supply store and bought screening, vs Home Depot, etc for window screening. For the front doors, we made what are called "bag screens" - you sew a 2-sided screen pocket, with the bottom left open, in the shape of your doors. Use by opening the front door, pull the screen "bag" over the door itself, close the door. Now you can open/close the door window as needed, but there is screen over it (actually both sides...). We use a strip of magnetic tape along the bottom screen edge on the outside of the door to hold the screening tight to the door below the bottom of the window so no bugs (I hate bugs...) can sneak in... Can't help you with the sliding side door, our Chevy has the 2 doors that swing open. I have seen the "disappearing" screen door as mentioned previously for the side door - very nice idea - likely a bit pricey. For the rear doors we have a large piece of the same tent screening that velcros all around the edges inside the doors - so the screen remains in place all the time, but no bugs (did I mention I hate bugs...) can get in if the rear doors are open. The commercial version of this for sprinters has a zipper all the way around vs the velcro from what I have seen. ST
