Do you mean Luxury Vinyl Planking or is LVT Luxury Vinyl Tile (may be a thing, I just have not seen it until now).
I had LVP installed, replacing all factory sheet flooring in my Sunseeker MH with 2 slides. Although the rear bedroom with 1 of those slide outs was carpeted and we left it that way.
In the combined living/dinette and kitchen slide out area my slide out floor is raised about 2 inches accommodating a dual rail slide out mechanism underneath. With this type of raised slideout floor it is easy to judge how much the floor height of the coach can be without being scraped by the slide out floor railing.
In my case, installing LVP was not an issue. My LVP is much smaller in height than the carpeting it replaced as well. Also, my coach had plywood subflooring, so no subflooring needed to be added.
My dealer removed the dinette and hired a flooring sub contractor to install the floor. Glad I hired pros. Installing the right product, the right way.
My two cents.
