It can be done in one carry if really stubborn but usually with two or three slogs.
The key is the magic duffle on the back which is really an MEC 125L duffle. Too big really, but offers lots of room to stow the miscellaneous items haphazardly strapped on when stopped. In regular use allows for with easy insertion of tent, sleeping pad, sleeping bag, etc. and plenty of room to spare. Once strapped down, you can minimize the excess folds of the bag.
Advantages of having excess space is that you can stop, unstrap, and stow the soft inserts from your Pelican cases in the bag. Bag is slung like a backpack on your back, left arm through the helmet, tank bag in your left hand, cold

in your right. Pelicans sit locked on bike but are empty.
Downside of this is that you tend to lazily allow the stuff in your panniers to work their way into the magic duffle at which you become overly top heavy. Bag is also not 100% waterproof so big kayak bag is required inside for any items you need to keep dry. Lazy, but with space to spare, packing and unpacking are much easier and no sorting and squeezing.
If using tank bags as well, not much can be done to avoid another trip. Usually too muddy to throw in the big bag, but strangely not too muddy to drag into the poor unsuspecting hotel room.
