Here's my latest set up - as of summer 2012 - my trip with my buddy Russ Perry (shown).
The left saddle bag had my clothes in the Yamabag. The right one had my 16aaa tennis shoes, tools, Qt. of oil, and other odd items. I tended to keep the trunk near empty to accommodate my layers, groceries, and such.
Since we camped every night - save one during those two weeks, the camping gear is shown on the rear seat. The orange is my 3 man tent bag. I added a Kneeling pad beneath it to protect the seat. Behind it is my 3 1/2 thick self inflating air mattress. Both get strapped down to the back seat by 2 ROK Straps attached to the GIVI grab bars. On top of this resides a small MotoFiz seat bag. That organizes my camp kitchen, campside rocking chair, hatchet, and other camping stuff. That MotoFiz expands on both sides and holds quite a bit. Attached to the far side is a 2 liter Camel Back with an extended insulated hose w/ bite valve. I use a keychain winder to keep it handy behind me at arms reach.
The lunch box thingy is actually a 12 volt slow cooker. It gets up to 300 degrees inside and is fused at 15 amps. I plug it into a Powerlet mounted in my tail piece when I cook while driving down the road. We used it once on the trip because I am a terrible cook. I'm getting better at it now.
The yellow dry bag on the trunk rack is my 20deg. sleeping bag and pillow. I use ROK Straps exclusively on all my packing. Between the GIVI trunk mounting platform and exhaust pipe hangers there are plenty of places to strap things down. The nice things about the ROK Straps is that they stay in place when you take everything off, and once set up everything clips right back on quickly.
The tank bag is a Bags Connection unit with the electrified fuel tank quick mount ring. My iPhone charge cord plugged inside via a USB to cigarette lighter adapter. My Sena unit also charged from here, typically while we were in motion. One charge between gas stops per day kept it going all 2 weeks. We both had GMRS radios but never used them because the Sena units performed flawlessly.
I'm pretty happy with my set up, it makes for a tight package with the weight close to center of mass. The bike handled fine loaded up. The extra bonus is that it gets better fuel mileage when the space between the driver and trunk is filled up.
One downside with this set up - which we did
not experience on that trip - is that my registration and proof of insurance is under the back seat along with the tire string kit and pump.
As you can tell, we kinda got muddy riding through the flash flooded areas on the ET highway in Nevada. Makes me glad I had on a fresh Exalto on the rear, I really parted the deep waters on one of those crossings.
I'm ready to go again !!!

Unfortunately I was asked by a Utah State Trooper for my registration when I went to Colorado last year with Beemerdons and Zilla and the AZ Beemer crowd. When he saw how much unloading I was gonna have to do to get under the seat he just asked me if the bike was registered in my name. Unfortunately he did still give me a performance award
