I just traded my 01' 3/4 ton for my new 07 3/4 ton. The new rig does not have the large motor and it feels like it (GM in it's infinite wisdom only offers one motor for the 3/4 ton). The vehicle itself is O.K. but there is just not enough power. My V6 Toyota 4-Runner will out tow the Suburban. My real problem is when it gets hot and I am towing. From off the line- the Suburban will barely go with my foot pushed to the floor. I know the computer changes everything when the motor gets to a cetain point but this is ridiculous. Any suggestions?
