In my campervan I've got a kitchen built from wall units stood off the floor on 18mm (finished dimension, approx 3/4") wooden battens. They're mainly to stop the doors scraping on the floor/catching on the rug.

I've never found the lack of space for my toes an issue, even with big feet, and I do cook properly in there. That I have to stoop slightly anyway for the ceiling height except under the skylight.

Cleaning is a bit of a pain, but I don't have to do it often in the van. Most effective is to get down on my knees and use either the crevice nozzle/brush on a vacuum cleaner, or a brush, followed by a damp cloth. In a well-used kitchen at home, this could get annoying pretty fast. In that either no gap or a gap that fits your preferred cleaning tools would be better than a small gap.
