Haven't had any problems with that personally. The holes you drill is to hold the lead piece at the front. Sheet metal size and I think three. Unless you also drill the holes for the hold down on each inside for the latches. I never drilled those and just removed a floor strip bolt and used a bungy cord through a eye bolt. With new bedsides didn't want any extra holes myself. Good luck and overall a decent product.
