About a month ago dusty1300 offered up a couple of hardcase trunk bags for sale. He had a nice Castle that was good sized and I took it off his hands. I had a soft trunk bag for a few years and it was not very big and a pain when it was empty.
His Castle was designed for a sissy bar type mount so I was able to use the frame of that to attach my smaller soft bag to the rear of the Castle. The weight of the soft bag lays on the passenger backrest so it supports itself pretty well. And I can simply tip my backrest forward to still open the trunk for access without removing anything. Still have room under the soft bag for my small bedroll.
Still need to make a set of straps to tie it all on so I won't need the bungies but winter is coming and I have time to mess with it.
But I took it out for a ride tonight and it sits well and stable.
So thanks Tom for letting go of the Castle. Makes my traveling a little easier.
