I turned my Rock Guard into a window shade. It has worked well for 3 years.
Like others I used two tywraps to turn the rock guard's top two hanging points into hinges. It simply requires tightening two tywraps around the connection point with the guard in place.
I then took two pieces of PVC and use them to support the front of the rock guard, resting one end on the belly band and the other on the Rockguard's lower latch.
To keep the PVC pipe in place, I run a bungee cord up the center of the PVC pipe and hook it thru the Rock guard's lower latch. The bottom end of the bungee cord wraps around a screw that goes thru the belly band. The lower bungee cord goes around the lower part of the screw and the pipe sits over the top of the screw. I can provide pictures of this if you like. I cut the lower end of the PVC pipe on an angle.
This mechanisim holds the rock guard in place in normal weather. In a severe weather with high winds I run another bungee cord from the lower latch to the belly band screw.
Just drop me a line if you'd like detailed pictures. You could look under Modifications/Preparing a 1991 Scamp
. I can't remember if I had more details there but glad to supply them.
The following picture shows two Bunge cords on top. These are not used. This was an early attempt before someone on the site suggested two tywraps at the top.
