The truck has to be new to you, not new in general.

For a Sect 179, the asset has to have a GVW of over 6000 lbs to qualify for the up-to $25K deduction, however assets under the 6000lb GVW could qualify for up to a $10K 179- so theoretically, a base Ranger would still fall into this catagory. Consult your tax professional to verifu this.
