Agree with above post. We pull 10000 pounds with 6.2 and 4.30 axle. I seldom use drive and tow haul in hilly terrain. Put it in M and control shifts yourself. I anticipate the hill, shift down before it starts to struggle and then use a gear that keeps RPM at about 3500 to 4000 RPM and 45 to 50 MPH using only moderate throttle. I never put my foot to floor and am not worried if I lose speed on hills. If that so concerned me I would have a diesel, so what if I get to top of hill a minute later than a diesel would. The 6.2 pulls hard in the mid range and I have seldom felt the need to run it much beyond 4000, but if you do it will really pull hard, but why flog it, its not a sin to slow down a bit on a hill!
