I have a 2000 3500 2 wheel drive with Banks Stinger Plus and about 9500 miles. I pull a 5th wheel of about 11000 lbs. Friday I took off and when I got to the freeway I couldn't get above 40mph in 5th gear and it smelled like the truck was burning up. Took the next exit and headed home. Before I got there everything seemed to be O. K. so I got back on the freeway and headed for the coast with no more problems. I get a little shudder in 2nd now when pulling out loaded but do not seem to have any problems solo. Could my cluthch have been slipping and if so any suggestions on upgrades to a heavier clutch?? By the way it's a 5 speed with 4:10. Thanks in advance
