OK I am getting to old and my knees are shot to be sleeping on the ground any more. I have tried using Air Beds for the last several years with some success. It seams like I always pump them up the weekend before to test them out and they look fine. Then on the trails I wake up in the morning and 90% of the air is gone and I am back on the ground FUCK NO. The last time out my son brought his 30' RV Trailer and we slept in beds FUCK YES. But since this is not always possible I am looking for an option thinking of maybe a cot of some type what are you other old guys using
