That's funny isn't it?

The carpet I fitted recently in my van (from Knox) fitted perfectly over underfelt so it's crazy that a moulded carpet can fit perfectly for some and not for others. I know floorpans can vary slightly, but not enough to stop carpet fitting properly. Mine was plenty wide enough to fit under the sill plates, in fact I trimmed a tiny bit off one side to get the plate to sit down better.

And Knox were great to deal with.... same day shipping..... I'm happy, I'll be using them again for sure.
