When the kids were young we would tent camp out of our SUV. Packing was tight but we always had a blast. We eventually got a pop up camper and then an RV. Back when it was tent camping, we would get to our site, unload and set up camp. The first stop was usually the local Walmart for groceries and other consumables we couldn't fit in the car. We usually stayed for a week and made a few more trips for supplies. I can pack a car including a roof rack carrier, but nothing that didn't come in with us came back home. We would give everything to our neighboring campers and it was never a thing. Meal planning is tough with many kids and variable weather. And there is always going back to the store for more drinks and those huge perfect steaks are on sale. Scratch the hot dogs on Tuesday lol. This was 30 years ago but everyone we gave stuff to seemed very happy. Maybe it was a different time, but I can remember neighbors at the campgrounds inviting us for meals and we would do the same.
