Given I don’t have a truck...is it worth renting a camper from one of those places? Seems like the money spent to rent one would purchase most all the equipment needed for many trips. I understand your point though.
I think he was just joking a bit, but as you can see, camping's not for everyone. You obviously have an interest, so don't listen to these shmoes, listen to this schmoe: give it a try! Figure out what you're comfortable with buying vs renting or borrowing and give it a try... but be sensitive to the fact that some of your family members, including you, might not like it and don't try and pound a square peg in a round hole. Like I said, I like it, the kids liked it, but not the ex, so we made a few trips without her and everyone was happy and I still take them occassionally... although that's slowing with college. Even within camping, there are degrees. I don't want to do backpack camping, but I also hate the car camping campgrounds where redneck Walmart shoppers pull up and unload all their walmart gear with their kids and run amok for the weekend. My favorite campground for tent camping, is a small campground on the New River in NC. It has a small parking lot, so you have to either canoe in with your gear or park in the lot and schlep your gear to the campsite about 200 yards using wheelbarrows they keep at the bathhouse. There are only about 20 sites so it's quiet and serene, gorgeous right on the river, cooler in the mountains and with that little bit of extra work having to pack your shit in, it keeps out 99% of the walmart redneck riffraff (literally I've seen people leave when they realized they had to pack their supplies in). It probably takes me an extra 15 minutes to schlep in my gear each way, but it makes for an infinitely more enjoyable stay to me. But others would be bored senseless.
You might check around too, there are some places that rent or even supply camping gear with a deposit... colleges, community colleges, maybe some city parks and rec depts.. possibly even REI. My advice is just plan it: meals, clothing, etc.... and try not to overpack. Take: lantern and flashlights, especially headlamps for everyone, raingear, sleeping pads, water jugs, music, liquor, book, bugspray, smore supplies or some treat, good firewood, campchairs, slip on campshoes, towels, simple easy to prepare meals (freeze beefstew, marinated chicken or steaks, PB, oatmeal, trailmix, fruit), trashbags. I'd go light on recreational stuff, it usually doesn't get used much. Maybe a football or frisbee, cards are good or Farkle or yahtzee. Everything you take, you have to carry to the campsite, and much of it back again, so the lighter the better and less work. Good luck and let us know how it goes.... Sucker!
