I just wrapped an 11 day mixed riding/working trip (about half the time I was stopped at my work's HQ on business). So i had to pack my work backpack (laptop, gadgets, notebook etc.), a week's worth of work clothes and several days worth of riding clothes, plus my riding accessories (tools, cycle pump, cameras, chargers, rags, etc.). I always buy gifts for the kids and grandkids while away so I had to have room for that as well. Also, one of the bikes in our group got totaled out so I brought home his fuel canisters.
The F6B swallowed it all up admirably, but two critical pieces of gear made it possible: the Bike MP3 luggage rack and my Motofizz Medium Camping Bag. No way I could have done it with just the saddlebags.
The reason I picked the Motofizz bag is that I own and have used on a long trip the large Motofizz, this one fits perfectly on the Bike MP3 rack, and it is an outstanding motorcycle bag. Supremely well built and versatile. Expandable side to side and capable with the upper flap of expanding vertically. A nice pouch on the side for a water bottle. Easy access zips for caps/beanies and cleaning cloths.
Here's pics of my bike with the bag installed.

I can say with 100% confidence that it would handle a 10-14 day trip. If you want to pack a lot of camping gear you might consider a second bag, or the large, or pack light. Sleeping bags and tents take up a lot of room.
I plan on taking a 10+ day trip around Labor Day to Crater Lake, the Columbia Gorge, Mt. St. Helens, Glacier, Yellowstone and the Tetons and the Bitterroots and that Motofizz medium bag will do the trick for sure.
Good luck and have fun!
