Depends on what kind of camping that you want to do. On this trip for instance, we camped at the campground. We took coolers, a big tent, and plenty of other things to make our trip the most comfortable. Every morning we had bacon, eggs, and fried potatoes (with plenty of peppers, onions, and even a little bacon). One evening we had grilled chicken and the other we had big thick ribeye steaks over the fire. So, needless to say, we weren't roughin' it that much.
If I were going on just a backpack trip, then I would focus on a small stove (Jetboil is a good one), a small tent (this Tent
is killer if you are alone), some form of water purification, and as far as food goes, I am a huge fan of rice cuz it tastes good and is easy to fix with just water, granola is another good item to have also. Don't forget a map, compass, and/or GPS (which don't always work under heavy cover). I am sure I am leaving out a few things, but these are atleast a starting point of the essientials....
Oh yeah, COMFORTABLE SHOES!!
