Has anyone successfully baked a good sourdough in a Weber Baby Q gas barbecue?

As per the title I am traveling full-time in my van at the moment and used to make sourdough but I'm trying to figure out the best way that I would go about it in a baby q.

I also don't want to use a heavy Dutch oven as I have weight restrictions with how much I can carry.

Any tips and advice would be greatly appreciated.
