As per Perry's concerns, Sign grade vinyl won't fall off, but yes indeed most of the vinyl that sign shops use has a tendency to shrink over time. If you went that route you would need to ask the supplier if shrinkage and therefore pulling away from the seams may be a problem over the long term. There are many different grades of product and you should expect they would need to order special order stuff in....With standard sign shop vinyls you can also have issue of the vinyl developing ripples from the repeated expansion and contraction that is goes through with temp changes. In short, most of the products I use at my sign shop I wouldn't recommend for that kind of application.
In playing with that factory original sample piece I cut off of my 1969 safari's wall and brought in to work I can actually see it has fabric fibers literally weaved through it, its not just a texture look. If that is what the fellow above who took his stuff to a sign installer to apply found, that would be the route I would recommend.
