My wife and I have been truck camping for 15 years and I totally understand your concerns. We live in western NY, south of Buffalo, and there's not a lot of "public land" open to overnight stays. We just drove to Alaska and back over 5 weeks, and paid to camp every night. To me I need the comfort knowing that I'm in my "legal spot" every night. I couldn't sleep if I just parked somewhere down a dirt road not knowing if I was on somebody's property and might get a knock on the door as you suggested. I just haven't figured out how to tell if it's OK to spend the night somewhere - it would be great to have a huge map of the US and Canada that said "OK to camp here, not OK to camp there", but I've not been able to find such a map. And there's also the convenience factor - wife on her Ipad, me driving, tired, 6:00 in the evening, she says: "Hey, there's a KOA in 5 miles". Me: "Sounds great"
