This is the Ultimate 4 Wheel Drive Chevrolet Tahoe Z71 Package and. on top of that. the cool 2 door version. What is the Z71 package? It is the GM code for "Off Road" Package. Beyond the standard equipment. it has the following build codes: KNP: Cooling System Trans. HD ("heavy duty"); NY1: Shield. Fuel Tank; NZZ: Skid Plate Off-Road; Z82: Trailer Provisions. Special Equipment. H. D. Beyond this it has leather interior which is in very good condition. Unlike other Chevy 2 door Tahoes being advertised here. this one is (1) 4 wheel drive (some of them are actually 2 wheel drive). and (2) it has the Z71 Off Road Package. This is a rare vehicle. Well maintained and everything works: A/C. remote lock. turn signals. etc. Have receipts for over $5. 00 in work since owning it in January. 2013 (with 84k miles). including work on brakes. new radiator. air conditioning. and steering. Includes highest quality Michelin All-Season tires. purchased in February. 2013. All issues have been sorted out the only down-side is the rust which has developed. which could be easily removed with some body-work. Ready to drive through the woods and snow.
