I bought some steel 1/2" conduit and a mess of fittings to throw something together but haven't had time. After standing behind my HMMWV with the various fittings for half an hour I believe I have a picture in my mind of how to put together a soft slant back, with hatchback of course, but I have to set aside the time to start and finish it with the plan running in my head.
I will document it thoroughly if/when I get to it. I want it done before winter to seal the HMMWV better against the elements. I'm tired of water intrusion from the bed area into the passenger compartment. Haven't bothered to put much effort into improving the interior as a result and want it a bit more tidy and refreshed.
Sorry to not have proof, but I do think I can see it in my head.
I agree that someone who could throw together a removable, but not otherwise accessible (no hatch) could probably sell quite a few. Hmmmm, maybe that should be me...
