When you screw down anything you removed while installing the floor just drill a 1in. hole through the new floor and screw through it. If the floor moves, and 2 years has not shown any movement, the floor will float around the screw.
You can see I removed as much as possible before setting the floor. This removes the need for 1/4 round at the base of things and makes for a faster install. To remove all the cabinets, coach and dinette took less than an hour with a drill screwdriver.
I removed the drawer of the coach and tied the coach itself up to the cabinet door above and only laid the floor about 6 ins. under the coach. No reason the waste flooring under there.
