I'm planning to do a Safari Cab sewing project in the next month or two. Every summer I swap out the hard sides for the soft sides, here's a photo taken near the summit of Mosquito Pass two years ago:
The way the current soft sides work, they replace both sides, the back corners and the barn door.
The way the hard panel modularity works, the hard sides can be removed while leaving the rear corners and the barn door in place. I don't have a great photo of that, but here's one I took when I was testing the idea of swing-up hard sides (the barn door is off in this photo, but it does show the rear corners still in place when the side panels are removed):
This summer I'd like to try running the Jeep a little different way - I'd like to have soft sides that roll up, but leave the hard rear corners and barn door in place. I don't really need the back to be fully open all the time, so I'd like to try just roll-up sides, which would still give me easy access to the back through the barn door without having to open the rear canvas.
It would look something like this when they're rolled down:
It's a pretty simple sewing project, the panels are rectangular and there's already provisions for attaching the panel to the bottom of the roof and the back of the front door surround. Attaching to the front of the rear corner will be simple, and I'll probably do just one large window as shown in the drawing above.
