Hey Finn, I'm getting ready to outfit my 390 with full Wolfman for Lite-Camping. I already have some of the Wolfman stuff.
How was the Small expedition tank bag (that was the Small right or maybe a GL?) between the 2 Large Rolies? Did it get in your way at all?
Probably more convenient than the small Rolie as a tankbag?
Thinking about this for the rear (3 Medium Rolies or Small and Medium mix)
using this rackless mount
Using your front setup that would be about 25 liters in the back and 32 liters in the front.
That should be enough on the Berg and still be tidy and trail rideable eh?
