By "car camping" I assume you will be using a tent to sleep in but will probably be setting it up within an easy walk to the car, perhaps what some call a drive in primitive site, maybe with a tent platform, picnic table, fire grate, and even a pole for bear bag and/or lantern as in many National Forests. The nice thing about car camping is that you do not have to worry about weight. I take heavier food and even when I car camp, and I have car camped for up to ten days or more in a Subaru Forester without resupply while camping at five different National Forest Primitive Campgrounds. On the other hand, I take nothing that needs to be refrigerated or kept on ice. I pack almost everything, food, cooking gear, clothes, and odds and ends in watertight plastic bins. I can simply pull the bin out of the car to find what I am looking for and do not have to think about anything getting wet or dirty as long as it is in a bin. It also helps to keep bugs and small critters out of the food. Since weight is not an issue, I carry a tarp to pitch over the picnic table, eating area, or over the rear hatch of the car in case of rain in addition to a tent. At one National Forest Campground I was able to pitch the tarp over the almost unmovable picnic table in such a way that I could back my Subaru up to it and open the rear hatch under the tarp so I could cook, eat, and access the plastic bins without getting wet.
one or more gifts or other benefits from the co-op.
