 We traded an '04 Envoy 4x4 for this because we trailer a dirt bike and atv. As it turns out, we can use this on the 4x4 trails near where we live. The gas mileage leaves a little to be desired, but the V8 wasn't purchased for amazing gas mileage. I get about 15 in the city and 21ish on the highway. With 1100 pounds of trailer in tow, we get about 19. I don't think that's too bad for full-time 4wd.
