As someone who has attended quite a few land use type meetings over the years, to include a couple recent ones for Utah National Parks, it's interesting to see how varied the desires and opinions are in regards to park management. Simple fact is they can't please everyone, and the National Parks will not be able to accommodate the amount of use that is predicted through future years. Public perception of RV's in general is somewhat negative, and there really aren't any groups out there lobbying for use so I expect to see RV'ing, especially boondocking type stuff, going away completely on public lands within 20 years or so. Entry to the parks themselves will almost certainly become restricted, although how the rationing or limitations will be handled is something I'm not certain of. The Park service is still trying to sort that out. They've currently had to close the gates for entry on Zion and Arches a few times that I'm aware of now because the crowds got to big to handle, and the projections are that the crowds will continue to increase for the foreseeable future.
If you've been to one of the western National Parks during peak season in the last few years you're probably quite aware how difficult just getting around the parks to the major sites has now become. While surface area wise they might seem big, the crowds are simply huge, and tend to want to all be in the same key areas.
