We have had Allure Ultra for almost 2 years of fulltime living. We like it fine, but should have used an underlayment because you can see marks from the wood underneath. The installer didn't do what the directions said and didn't leave 1/8 inch space so we've had some buckling. His fault, not the fault of the flooring.
Here is the link I posted on my blog.
A few years before that DH and I installed the old style Allure flooring on our previous motorhome. It was the Allure that had the glue strips. It was nice, but when a slide leaked, it caused the glue to come undone and we had to replace a few planks.
Hereis the link to the blog when we did the installation ourselves. By the way, we DID leave the 1/8 inch gap as instruced by Allure and never had any buckling!
We have had no trouble with the Allure that was the fault of the product. We are fulltimers, so the rig is not kept in cold climates with no heat, or hot climate with no AC. It has worked well for us, but next time I would put down some nice smooth underlayment first because in time, even those thick planks will show what's underneath.
Feel free to PM me if you have any questions.
