Good point about the clutch... I am planning on a new centerforce once I hit 100k or so. I really don't do much heavy towing, but when I do, it's HEAVY, like the 36' triple axle gooseneck we loaded with 15,000 lbs of steel (+trailer weight of 5000) this past weekend. Annabelle pulled it like a champ in 5th (direct), never got over 55mph, held right around 800 EGT, 10psi boost on level ground. I don't need to get too wild, just something to give me a little extra when I need it and not put a strain on the engine.
