OK OP Is likely long done that short trip By Now.

just sharing further considerations on this theme..


A Trailer Bag with Back Pack straps (so you can 'wear the Trailer if Needed),
Vs 4 loose Panniers + a Handle bar Bag + the rear rack-top stuff sacks , is a big difference when Off the Bike ..

... and in places like.. a path you could walk thru But the bike + Panniers is too Wide & your stealth camping spot is a 1/4 Mile on the other side
or a stone fence with a stair way Up and over it is the only way in ..

or places like the Hostel in Warsaw PL which was up a High staircase to get to the front door (it was a old Stalinist designed Govt Building )
would require a a Lot of trips with panniers and Bags in your hands ..

So Where do you plan on Going and how will you cope with the way your kit is Packed ?

[my example: I just took an Overnight train to a SW Polish town, and rode into Prague the next Morning , instead]
