To me it is worth it. Very easy to wash and clean.
I've had the peeling decals and fading fiberglass problems on my past M H's.
I'm sure the ones made today are better than those made in the past, but they will not last like a full body paint.
I have seen R V's with FBP that are many years old and still look like new.
Maybe you can't get all the cost back, but the ease in keeping it clean and shiny sure requires a lot less effort.
