Just explain that you replaced the step rails with rock rails. The step rails would just break anyway...that's why they are hanging in the garage.

Examples of Further Ammunition:

The stock rails (Wasting precious storage space in the garage) can be sold on e-bay, etc. (First - so there are none in the garage)

Once garage is emptier...Wow, its really a pain to climb up into the truck! Oh, look, a great sale on new stronger rails that don't have to hang in the garage!

Side impact protection - Need strong side rails to fend off shopping carts and people on cell phones, etc.

Its my truck bitch, do I tell you what make-up you can buy?
