Why not a Fuji? Fuji makes superb MF cameras with great lenses.
I carry my G690 with 2 or 3 lenses everywhere I go. The problem is that it's a little on the heavy side and I prefer to travel light. Here's the trick: I have been on a diet for a few weeks and have lost 6kg. That's much more than the weight of my whole photo bag!
If the big 690 series seem overkill to you, remember Fuji also makes nice 6x4.5 rangefinder or autofocus cameras. They are perfect for travellers: easy to use and lightweight.
Cheers,
