2005 Specs,Trailblazer LT
 

Anybody have them?
I'm looking at a 2005 with the 4.2 liter engine, rear wheel drive and automatic transmission. It has a trailer hitch and wiring. The dealer says it can tow my 3000 pound boat, motor, trailer.
Need to know before I spend the money for a mechanic to look at it for me. (It's being sold As Is, no warranty or service contract.)

if the vehicle has the owners manual it will say in there.
the axle ratio and rwd /4wd configuration will make a difference.
