My wife and I usually camp in our truck, which is a 1995 Mitsubishi Montero, mentioned in the squatching vehicle thread. We took all the seats out of the back and made a sleeping platform and slide-out cutting boards/cook stove surface. My wife made the curtains for the sleeping area.
For backpacking we have a small, waterproof Nemo tent. It's very minimalist, and has a tiny footprint which is useful in the Cascades. In my single days I used a Hennessey Hammock with a Hammock Gear down underquilt. Quite comfortable and pretty effective in our rugged terrain here, but useless for two people.
