I had a US20, a US5 for documents, passport and cards, and a RS 15 back pack too with the added hydration pouch. That did me 2 weeks but I was wearing leathers and the same t-shirt the whole time. I just washed it in the hotel sinks and had showered and changed at the end of every days riding. [emoji40][emoji90]
3 or 4 nights, I'd use a tank bag. That's all you need. You're in your bike gear all day. 1 set of clothes for the evening, clean crackers, socks, razor, toothbrush, comb because it's smaller than a brush(delete if not applicable). Rain gear, chain lube, credit card, passport, insurance. On yer bike, happy riding.
I used a US20 with two US10's either side with flip flops in between the 20 & each 10. As has been said pack light and I say try to avoid the rucksack. I took a R35 to Nurburgring on a R6 for a four day trip, big mistake. Pack your toiletries and change of smalls in the front of a us10 and remove whilst on ferry to take to your cabin or chair. Look on YouTube as loads of people with good tail pack, packing videos. You only need what YOU need..
