flooring dilemma

Why not call Newmar and ask how critical the floor height is for the slide?

As we used to say in Maine, "That Ernie is wicked smaht." :)

Heat is your friend. Do small areas with a good stiff putty knife...heat the area with the blow dryer, maybe 1sqft, and peel it up.

I'm planning on doing this same thing...once I pick my flooring, which will likely be Allure Vinyl planks.

pry those vinyl tiles up. the floor will be sticky. Get some Durhams rock hard water putty at Homey. Don't mix any water with it. Dust the material and spread with a broom. That will neutralize the sticky floor.

There is a foam underlay used for laminate. I know that many vinyl click products do not require the underlay but there is no harm in using it. Add the number of layers of this foam underlay in the low areas to bring it level with the existing tiles. Quick easy and inexpensive way to add the required thickness to the existing floor.

If the levels differ a small amount then likely no issue as the vinyl products have some flexibility. The current difference of 3/8 is too much and would be noticible.

I plan on ripping out the carpet and putting a laminate floor in. The carpet is no problem, but the tile in the kitchen won't come up. I plan on buying the cheapest stick-on tiles I can fine (some are $.39 each) and putting them down to make the floor level, then put down the laminate. Maybe this would work for you.

Just a thought: Open the slide and look from outside in, lifting the flexible flap. On mine, the stationary rollers on the floor would have to be worked around, but it looks like there would be no interference. I've seen a big variety of motor mounting locations on slideouts, some on the floor, so that would have to be worked around, also, but would be out of sight line.

Maybe look closely at various locations as you open it a little at a time. Or lay down some test pieces and operate the slide a bit at a time, seeing if you can freely move the test pieces.

I wouldn't try to take up something bonded to the plywood, myself. I've done that with structures that had adhesive, and the top layer of plywood always seems to get tears and holes in it, or else you end up with lumps of the other material you have to chisel off.

Try to remove some of the vinyl flooring and see how it comes up. The adhesive may be weakened with heat from a hand held hair drier. If it is 3/8" thick, you may be able to take a circular saw and adjust the blade depth to help cut the flooring in to manageable strips for removal.
I would suggest that before you put down your new flooring that you put a couple of coats of polyurethane on the sub-floor to seal out any odors and to help protect the sub-floor from any leaks/spills.

Height differences are common.
Go to a good flooring specialty store and get a transition strip to match.
Good Luck, Mike

I am thinking about laying my fake wood flooring right over top of the old vinyl flooring. The carpet is a higher where is transitions to the old vinyl floor. I'm hoping the my new flooring will match the new height.

Hard to say without seeing it exactly, but if you choose to remove it, you may wish to purchase an electric multi-tool also known as an oscillating tool. There are a variety of different types out there but you can pick one up for under a hundred bucks. It will make removal of the vinyl much easier.
