I’ve used everything – vinyl, metal, wood, fiberglass. The bottom line: as long as you paint it, it all works, but that’s based on your expectations. All the skirting is designed to do is to cosmetically hide the ugly space between the home and ground. That said, it sometimes is also a focal presentation to make your park look better. I would stick to vinyl on the most visible homes, and then retreat to something cheaper and paint it on the homes that are not that visible. If you can afford 100% vinyl, then I’d go with it, because it is the best as far as looks and life (as long as you don’t weedeat holes in it). To guard against doing that, put a row of shingles at the front edge of the skirting, so grass cant grow near the skirting and you won’t have to get a weedeater near it.
