The flooring came from my favorite RV supply store, IKEA. But they have discontinued the laminate flooring line so you will have to try locally. I suggest trying to use "Engineered" flooring, it's wood on a substrate and less sensitive to water spills than laminate. COSTCO has some nice flooring as well.
I cut the flooring to fit within 1/4" of the cabinets and then used 1/4 round edging. Works fine and the floor has the expansion spaces it needs.
If you are up around Riverside area send me a note and stop by to see my Hunter if you would like. I am just off the I-215 near March AFB.
