Overview
Sure you can get a truck with all kinds of fancy-pants features, but some folks just need something for the job. Enter the Chevy Silverado 1500 WT, or Work Truck. Available in myriad cab and bed combinations, the WT comes standard with a high-output four-cylinder engine. However, buyers can upgrade to a 5.3-liter V8 with a 10-speed automatic transmission as well. Two-wheel drive is standard but four-wheel drive is a common upgrade. Don’t expect any luxury on the WT. It’s so basic Chevrolet has to brag about USB ports. However, some advanced driver’s aids like lane departure warning and automatic emergency braking are standard. When properly configured the Silverado 1500 WT can tow 9,500 pounds.
Key Features
- Available in regular, double or crew cab with a standard, short or long bed
- Two engine options
- Four-wheel drive available
- Bench front seat
- Rubberized vinyl floor coverings
Pricing Details
The least expensive way to get a 2022 Chevrolet Silverado 1500 WT is to stick with the regular cab, standard bed, two-wheel drive and the 2.7-liter powerplant. That combination comes in at an MSRP of $36,395. If you choose a crew cab with a standard bed, four-wheel drive and the 5.3-liter V8 the price rises to $47,585 MSRP. Used examples on CarGurus range from $5,477.00 to $43,778.00 with an average price of $10,651.00. A WT convenience package with rear window defroster and cruise control can be had for $650, or buyers can go bigger and add hitch guidance and a trailering package to those options for $1,045.
