Not that I know of, but there are plenty of opportunities to camp for free in plain sight over much of the country. On the Trans America for example, it isn't very hard to average <$5 per night. On the TA this can be done mostly using sites listed on the Adventure cycling maps, but on other routes it is also possible. The Southern Tier was similar in that regard. It is usually pretty easy to find free camping in the middle of the country and a bit harder as you get closer to the coasts. I have found that rural small town parks and picnic grounds usually work out well especially in the great plains.
But you asked about hiker biker sites so I'll add... I have only run across hiker biker sites on tours here and there other than on the pacific coast. These were often in National parks.
