flooring
I installed Laminate flooring in our bus. Tip to tail before anything else went in, then built on it. My bus has a solid metal floor, then stock 1/2" plywood, stock rubber floor, combo insulation/vapour barrier 4mm, then the laminate. Heat wise, not a great insulation. However it is better than just the rubber.
Durability was great during the build process. Very strong and scratch resistant. All was going well until I tested the water system, and had a couple of leaks. I was ready with towels and sopped up the mess right away. The problem was that moisture was trapped between the vapour barrier and the flooring. I did what I could to dry it, but it did raise the seams and cause it to warp. Some area's worse than others. The main living area that gets the worst foot traffic is still in great shape. We camp in all sorts of weather with two big dogs (moisture sitting on the floor is common) and it has held up well.
So If I were to give advice, it would be ensure the entire floor surface is sealed. Good tight seams, and use a flexible sealant like clear silicone on the edges where the floor meets the walls. This way it still allows the floor to float, but reduces the chances that the same problem will occure that I encoutered.
Take a look at my photo album for pictures.
