We installed TrafficMaster Allure in our fulltime 5th wheel and it worked very well for over 6 years. Then, last year, the edges started "cupping". Made it difficult to sweep and of course didn't look very nice. I contacted several Home Depot carpet associates and the consensus was that I hadn't allowed enough perimeter gap. I bought new product, made sure the gap was sufficient and this time rented a 90# roller to run over the seams. If we get another 6 years out of this we'll be happy as DW will probably want something different by then anyway.
