"I have seen many that appear to have pulled their trailers up to the hills, parked them, and have left them. They now have a "permanent" camping spot on public land to use at their will. They visit every so often and, at least I hope, will tow them back before winter."
And in this the FS does have a "day limit & distance" set of rules (something like no more than 20 days at one spot and not closer than 30 miles for another spot). If folks report a vehicle parked - it could be reported and the FS could monitor (day limit passed) and then hauled out.
Granted, this wholly gets into the "FS doesn't have the resources" issue. I could see the FS get more involved with sponsoring clubs. A sponsor could monitor (& document) with the FS and once the day limit is past, the club with local sheriff / towing company could get scheduled to remove the trailer (local club towing out to public road). I could see sponsoring clubs willingly getting involved in such a task.
