remember that sometimes those openings are there to allow access to wiring, plugs, bulbs etc. the other 2 in dents are where the grab handle mounts if its ever wanted in the future--threaded holes are already there. the holes are covered in my end result, but i still have accessView attachment 152524
I'm going to use a 4 way stretchable carpeting, if I recall it's used for automotive purposes, maybe called trunk carpeting, but it has no backing and is very stretchable. What I'm going to attempt, is to use some sort of insulating peel and stick foil, and carpet over that, if that will work. My other thought is to fill in any depressions and voids or holes with bondo, then carpet directly on the metal over a smooth surface. For me working with bondo is easy and I'm familiar with it. I did my old econoline that way and it came out great. For my purposes the carpet is my finished product, it's a cargo van so the interior won't be finished with any cabinets etc. I'll also likely do the ceiling in a similar method.
