I got a vinyl floor at one point.. I hated it. I couldn't get it to line up, it was hard as a rock in the winter time. I was always trying to kick the corners in.. grr I'm getting annoyed thinking about it right now.
That said, I ripped it out, threw it in the dumpster, and herculined my interior. One of the best things I've done to the interior to date. I wouldn't even consider doing anything else.
Just my .02 -- I'm sure others have had better experiences with the vinyl. But the majority of CJers I've noticed go with the herc/raptor/monster/etc interior.
