Linoleum sheet vs planks vs floating wood plank flooring?

Floating wood plank will buckle.

Linoleum if installed correctly and stapled down securely around the edges with quarter round or similar will endure the temp changes.

I used Pergo wood plank in our previous mh
Other people have used Alure
Prep and winter storage conditions are two big factors
Wood plank stays flat , unless you get water under it, the top is water resistant

We used Armstrong sheet vinyl in our last motorhome (Bounder). We did not do the slide or around the driver/passenger seat area.
We removed the carpeting in the kitchen and bedroom.
We used quarter round around edges. Looked good.

We are in the process of changing our flooring and will use the sheet vinyl flooring. We will get a good quality flooring so that it will stand up to RV use. Just seems to be the best fit for us.

A friend who builds houses got samples of assorted laminate plans and soaked them in a bucket of water overnight. That was how he determined which kind to install. Seems like a good technique, particularly for a bathroom.

Personally I would go with a sheet flooring that looks like wood plank flooring if you want to eliminate the buckling issue. Thats what we have in the new trailer and the wife loves it. Downside is it can be cut or gouged like all sheet flooring so the tradeoff is the planks are probably tougher.

Keep in mind that plank flooring products like Alure come in vinyl so they can get wet

I installed a vinyl imprinted laminate interlocking plank in my trailer five years ago. It looks like the day I installed it.

FWIW, I have a covered under-belly and installed a rubber underlayment under the plank, which also has an attached backing. The laminate I installed was one of the cheaper ones on sale at Lumber Liquidators.

If you live in the PNW or are one of those campers that can't keep water off the floor, I'd suggest to use a laminated plank that is made for wet areas. Pergo brand is one brand that makes such a product.

Sheet vinyl, if installed correctly, is impervious to water. The subfloor is not.

Put Pergo down about 7 years ago. If installed properly, leave a quarter inch gap around the perimeter, it will not and has not buckled through all sorts of temperatures.

Installed Allure a couple of years ago. It expands and contracts leaving gaps. Should have used sheet vinyl instead. I was afraid I would cut it wrong. If I did it again I would use underfloor paper taped together to make a full-sized pattern.
