* lift your travel top, up, from the ceiling/rafters/etc.
* figure out some way to lift it from something ground-based.
I can't think of any positive ground-based methods right now, off the top of my head, to do this. I recall from my youth, seeing pickup based bed-campers that had jacks on the side, where, while camping, those side jacks could be used to lift up and level the camper. Like this image for reference:

Even if removable when not in use, I'm pretty certain this isn't something I want to do to my traveltop.
Are you really expecting your 800 to go around topless a significant amount of time? Maybe just have a few buddies lined up for removal and re-install when needed?
I'm really digging here. Sorry this wasn't of more help.
