Found a great cover made by Budge for my new to me 04 Starcraft. Less than 70 bucks and appears to be made of Tyvek. With roof top air it provides plenty of air space between the camper. Living in a pine forest I'm trying to keep out sap and pine needles that can find their way into stuff. We'll see how this one holds up and I plan to open up the camper regularly to inspect and dry out. My camper has always been installed inside storage from previous owners as I'm planning on building a metal roof over it and will probably always keep it covered to keep clean.
