Pergo is a brand name. Engineered wood is a process with multi layers of plywood and topping it off with real wood veneer. Dimensionally stable, and tongue and groove is way easier then the click together products to install.
Slide Slickers are too expensive. Go to a retail flooring store and see if they have some luxury vinyl planks in stock. Those are super slick, then yet dense. I had some left over from a job and have given those to other clients whenever there may be a slide issue
I was working with a client who had a Foretravel. He was nervous as a cat by a rocking chair about the fact that they only had 225 pounds per axle before they were over weight. They fulltimed and I did not see an over abundance of items in the coach. He said they have been really diligent about not acquiring stuff. He was so nervous I told him to take that coach back to the factory to see whats' up. Haven't heard another word.
The work is labor intensive. A residential flooring person charges by square foot or square yard. Those guys can move pretty fast, covering large areas in a day. A coach is a whole different price point.
