This is my Thorn Nomad on a recent trip through Israel. Sort of medium-heavy I'd say—I had a roomy Hilleberg tent, but the weather was mild enough for a very light sleeping bag. I carried a Lumix GX8 camera system and a 13-inch Macbook Pro, a solar panel and a lithium-ion power pack.
I didn't have any trouble with rack bolts, even in the Negev. I do use blue Locktite.
