I'd love to know your secret. I'm an avid motorcycle camper and amazed you fit everything you need in those 3 cases. I'm also impressed that you don't need a tank bag. My typical trip is 2-3 weeks. My sleeping bag, 2-man tent, food, water, clothes, spare fuel. etc. take up more space than your setup. That's only for 2-3 weeks... you're out for 2+ months? Camping every night? I'm impressed!
Also, one of my only dislikes about my 950ADV was the limited range on a tank of gas. Do you carry extra fuel? How much? There are a number of places in the Western U.S. where the 950 requires careful fuel planning (HWY 50, for instance). 8000 miles around Mexico must've been challenging. Any issues with fuel?
I camped, but not every night! I usually stayed in a Hotels if available (the rates are cheap enough and a *possible* warm shower are worth the cost!
The secrets to packing are a very lightweight tent and sleeping bag (it was a bit cold in Parque National de Constitucion, BCN in late December -- below freezing!) and also, I packed clothes in plastic bags that are like a ziploc but have a one-way valve to expel air. They make your clothes look freeze dried -- and save a ton of space. Also lightweight tool choice (like aluminum tire spoons that double as axle wrenches). Think long and hard about what you might really need. You'll be surprised with what you can do without! I had mostly tools, spares and oil in the rear Pelican case, and everything else in the Jesse bags (they really suck up a lot of gear!). Initially, I had everything packed away, but after a couple of days, I found it much easier to pack if I strapped the tent to the seat in front of the Pelican case.
Another thing is the choice of clothes! Some clothes (like blue jeans) just don't pack down well and get dirty (or look dirty) quick. I had quite a bit of clothes I bought from a Mountain Hardware factory sale, and others on the trip commented - "How come you always look so clean?".
Gas was never a problem... the rule is, if you have less than half a tank, if you see gas, stop and fill up. Don't assume that gas is available ahead.
I made it all the way to the state of Chiapas, literally just across the border from Guatemala at Lagunas de Montebello. The rear tire was the only issue... it was brand new at the start of the trip, and nearly bald for the last couple of days (including Copper Canyon), and I made arrangements to get a new rear tire on the way home in Tucson, Arizona. It definitely wouldn't have made it home to the Bay Area (at least safely).
