Thank you for getting the label. I was able to go to the Lippert web site & found their 3 season door. Issue I would have (looking at the install documents) is that the frame is mounted 9" in from the ramp to allow closure w/ the deck gates. I have the two happy-jack bed riser frames right there. And when closed the deck railings are only 1" , or less , away from the beds. This is probably why Jayco provided a pull down screen (which has to be all the way up when closing the ramp door), but not a 3 season door option (not enough room).
The only way I could see putting one in would be to unbolt & move the Happy Jack bed assembly deeper into the camper. But I am sure there would not be the wall supports needed. As I have found out when mounting other items to the wall where the drawings said a support was / is,, NOT....
Or I could remove the railings each time, as the 3 season door would go in the "space" where the current deck rails are when folded. I would also have to figure out where to store the side railings when not in use & traveling. Just not worth the effort either way for the gain.
I did see where Morryde has an inflatable "room" for the party deck that can be sealed off, opened up , etc. Nice idea, but not sure of the long term (over the years) reliability for the the cost.
