One of the first things we did in our popup was to install a memory foam mattress pad. But this extra foam created too tight of a squeeze when popping the camper down – hitting the door when placed in the storage position between the mattress and roof. So, I moved the door!
I crawled inside the camper when popped down and noticed that the door was hitting the bed, but that there was a fair amount of extra room above it (between the door and the ceiling).
So, I raised the door storage plate a tad bit (only 3/4″ or so). This gave me exactly the amount of extra room we needed to lower the popup roof down on top of both the memory foam topper and down comforter.
