I ran the original style marathon deck which i had for over 11 seasons and had zero issues with deck. The Denali looks just like that one and I purchased the Nash last season and they look almost the same. What I found is bolt thru box with plates underneath to hold deck but also use turnbuckles for when loading and unloading it takes the rock out of deck and seems to hold more secure. So I only have 1 season on the Nash but didn't have issues.
