2006 Chevrolet Avalanche LS 1500 4dr Crew Cab 4WD SB (5.3L 8cyl 4A)
Versitile, rides like a large car, but still able to handle non paved roads with relative ease. Good power with the 5.3L v8. Hwy mileage is closer to 19.5mpg on level roads at 65-70mph. Easy to convert to pickup with the midgate. Love this truck.
Mid-gate, removeable rear window and hard locking tonneau cover. OnStar is fun but kind of expensive at $17/month PLUS minutes.
Standard equipment with the Z71 off road package should include an off-road type tire like a BF Goodrich AT instead of the Goodyear RTS.
