Replacing sheet vinyl with rigid vinyl planking

I was able to use 1/2 plywood on the floor of a TT once. I just installed it right over the top of the old floor and screwed it down. It just fit perfectly under all the doors and drawers. There was a little aluminum kick up piece on the inside portion of the entry door. By removing it the plywood butted right up against the door frame no problem.

Then I sanded the wood down and used some of those Sick On Tile Floor squares that looked like hard wood flooring. No one ever noticed a thing.

Do some measuring, looking, and thinking and I bet you could so the same thing.

My floor was not soft. But neither was it truly level. Thick flooring left gaps. Flexible thin flooring conformed to the "hills and valleys".

That's nice but I was giving advice to the original poster that stated, "Have a few spongy spots in the floor of our TT since I did not seal the roof properly."

If the floor is soft do not use any kind of snap together flooring. When the floor flexes the joints will come apart. Pull up what you you have. Cut out the rotten floor and replace it with solid plywood. If you intend to use it as a deer camp you will need to fix the floor anyhow. Once you have the floor fixed you can put down the vinyl planking. Or even the 1 x 1 sticky tiles.

As ScottG stated, this stuff can be very heavy. I put some in a finished basement and it weighed in at 50# for 25 ft2. The manufacturer also warned about installing where temps could drop below freezing.

Free floating floor is usually recommended. I put in Allure (big box) it was easy install and looks great.

The problem is RV's shift. So get thin vinyl planking. DAMHIK.

Do you mean something like Pergo? If so, just lay it down like normal without any gluing.
It's heavy though.
