I've only done some overnights camping trips with less then 15 lbs in some rear panniers and a handlebar bag. I was out riding last night along some beat up dirt roads filled with big rocks and potholes. The Fargo just sails along, I love it. I'm planning a longer weekend trip this fall in northern Maine, camping and exploring the dirt backroads there. The Fargo should be perfect for that type of ride. I hope to use it next year on a week trip along the Great Divide route. I run the stock WTB Vulpine's, which roll very well and with all that volume really smooth out the road. And of course, Fun Guy Green is the only color a Fargo should be, its the fastest ;-)
