I have a 1996, 2500. I have engine upgrades. My truck was 180 horses new and 440 ft. lbs torque stock ( California ). I now have approx 275 horse and 500 ft. lbs torque. I also have air bags and an exhaust brake. I tow a 30ft fifth wheel approx 10,800. The cummins is a great motor. This is my question? regardless of power I own a 3/4 ton chassis. I want to downsize the trailer to a 27 footer and hook a motorcycle trailer to the rear of the fifth wheel. The bike trailer is 5000 lbs and the average weight of a 27 footer is GVWR of 10000. This will keep me under the length limit also. Anybody do this and how much max can I tow ? Thanks for any input. Dale
