You are going to have to learn to travel lighter!
You might find BMW hard luggage too restrictive, and you need to watch what type of throw over panniers you have.
Throw over saddle bags and a tank bag is all I would be taking. The tent you can stow on the bike elsewhere, external to the bags, but it going to have to be small and light. But your bed rolls, sleeping bags, emergency rations, and cooking equipement, etc, are going to be in the panniers - divided equally between the two. It don't leave much room for clothes. You are going to need to wash them. And they are all gonna need to be in water proof bags.
Your maps, docs and valuables are going to be in the tank bag.
I am not actually happy riding with a rucksack on for any distance at all. But might go with a small light 'day sack' for when I am camped at a base came and am riding out from that location.
Leave the kitchen sink at home, keep changes of clothes, i.e. non riding gear, to a minimum, stuff that folds up small and does not need ironing. Restrict the Missus to one pair of shoes other than her riding boots - and not heels.
Boots - you are going to have to be able to walk in them as well as ride. Many riding boots these days are not really comfortable enough to walk in. Same with your other gear. Everything has to be multi-functional and not too focused. I am a fan of Army High legs, rather riding boots.
The trick is to have the sort of riding gear that can be adapted to the conditions, usually meaning a textile suite that has cooling vents and is still waterproof. Black leathers are probably not the answer.
Either that or do hotels - that way you do not have to take camping gear. Or at least have to flexibiltiy to revert to hotels, etc, for when the weather turns on us.
But you alrready know this don't you?
