Edited to add : I have the medium Vaude Silk Road, usually on the front rack of this bike.
This bike can carry up to 4 panniers and 2 trunk bags, or more likely, front trunk, panniers, and tent, sleeping mat & bag, etc. on the top of rear rack. Panniers hang outside and below all on separate rail. Useful for bike camping and unpaved/gravel road trips. Can haul a lot of groceries, too. Either way, bike tools stay in saddle bag and my personal effects go in the trunk bag up front for easy access.
