For backpacking, weight is a critical factor. We use a lightweight tent (3 lbs) neo-air mattresses (under a pound each0 and down 20 degree bags (about two pounds.) So for the two of us we are carrying 7 pounds total.

Car camping? We just bought an old Ford Van. Our tent now weight about 4,000 pounds. But the rest of the stuff is the same stuff we use for backpacking.
