Razorbackers, welcome to iRV2.
The 4WD Silverado is easy to tow - just put the transfer case in neutral, put the transmission in park, pull a fuse and go.
The 2WD version requires a drive shaft disconnect or a transmission lube pump. If you go to
Remco Towing, click on "Application Chart" and select your model and year, it will take you the appropriate equipment required to tow your truck 4-down.
