I put Allure in our 1978 Wilderness last summer. Allure does not recommend installing their product in camping trailers. I did notice that, as the temperatures cooled in Nevada, that there was some shrinkage of the planks and the joint were not as tight as they had been. We sold the trailer so I didn't get a chance to see if warmer weather would reverse the shrinkage.
You have to be very precise in laying out the floor around the many corners in an RV because any mistakes will be reflected further down the floor and will be impossible to hide.
