Armando since i travel by car and caravan i take a few bags, a think tank airport essential and retrospective 10 and 20, a tripod and a bag for some gear for possible maintenance. My Zf not a back-up camera this time, my z lenses 20, 24, 35 , 50, 85, 105 and f mount 300mm f/4 and voigtländer 180 f/4 etc, etc. Last but not least, the Z 40mm f/2 a handy little lens!
I admire your determination as well as your photos, Fons.
My wife and I used to travel by caravan (we call them travel trailers here in the US). We started out using tents and progressed through fold down (AKA "pop up") trailers, standard trailers and large "fifth wheel" models (the big heavy ones). Then my back deteriorated to the point it put an end to that. But I carried a ton of gear on our trips, from 35mm SLRs and Leicas to 4x5 field cameras with changing bag and multiple film holders and tripod. As time went by, I just went with two DX or 4/3 bodies and a couple of zooms...even once with just a Canon G10 compact.
