im looking at a truck but it doesn’t have a plow prep package. The sales guy said it has the Z71 package and heavy towing packages. And that gives it the plow prep package with the heavy duty axles, bigger alternator, and skid plates. Is this really true or just sales guy BS?

On the trucks that I have looked at, I can tell you that they are not the same. You get one or the other from what I have seen.

Z71 Has a lighter front GAWR up front than a plow prep truck.
Plow prep you cannot get a sunroof
Plow prep also deletes the built in garage door openers
Either of them do give you the skid plates though
