I am very satisfied with the fit and look of the A.T. Tri-Fold cover. The only issue I had was the box side rail guards sit approx. 5/16 of an inch higher than the front of the box so there was a gap across the front. The solution I used was a 3/8 inch stick-on weather strip purchased at Lowes ($5.00). I have driven in snow and rain with very slight leaks at the corners...nothing that creates issues for me. Protects my tools and luggage just fine.
