Thanks for the PM--so you want back movements and a Graflok back. In wooden field cameras Shen-Hao, Chamonix, and Wista have varying rear movements, and among metal field cameras there are Linhof, Toyo, and Wista, and there are others. Another monorail for the field that will do what you want is the Linhof Technikardan.
Extensive rear movements are a convenience, but there are often ways to achieve the same movements indirectly. For instance, if you have front and rear swing, you can swing the standards in parallel for rear shift, and likewise for rear rise/fall, if you have front and rear tilt. If you've got front swing and shift, you can do an indirect rear swing by using swing and shift on the front and rotating the camera, and likewise for indirect rear tilt, if you have front rise/fall and tilt. With a field camera one is usually trading convenience for light weight and sturdiness, but it's worth noting that the Shen-Hao and Chamonix cameras have extensive rear movements for folding wooden cameras. Just note that some of the earlier Chamonix 4x5" cameras had a design flaw that caused a groundglass registration problem, so I wouldn't purchase a used one.
A Sinar F/1/2 is certainly a backpackable camera that doesn't take long to set up, but I think I'd find it a bit bulky. It's a good architecture camera, because it's quick to use, has full movements, and is easy to transport by car, and architectural subjects tend to be accessible by road.
The Sinar Alpina/A/A1 has a more compact rail system, so it's more suited to backpacking, but of course that means that the rail components aren't compatible with the rest of the Sinar system, if that's important to you.
