Before deciding to transform our Renault Scenic into a camper I made a cover to hide everything in the back when we were camping. As we left the back seats at home and got the back full of camping stuff we wanted to hide it from the outside view so I made a panel that was supported on the back doors with CAD (cardboard aided design) I used adhesive felt to protect the doors and the back tray just stood above the panel for a seamless fit.
The only “downside” is that know that we can sleep in the car we don’t use the tent anymore so we don’t have a use for it.
I hope you enjoyed!!
