Click-Stand -

I use this with my BOB. I have no affiliation with the maker of click-stand. Just find the product very useful and handy. They have "tiny bands" that you put around the break so the bike doesn't take off on you, and then you unfold the click-stand.
I have used it on my loaded bike with a loaded BOB and it holds pretty good. You do have to be a bit careful about the ground not being too soft, but that will be same with any stand.
