I'm being told this package is mandatory when ordering a Denali Ultimate. Might be the case with other models too but that's what I ordered. Is this correct? Anyone else hear this before? It's a $1,540 option that I don't need or want. If I do in fact have to get this will this mean I will have extra holes in the bed of the truck? Sorry if this is basic knowledge but I don't the answers so I'm asking.
