By my sig, i pull with a 2002 8.1.....Its specs are roughly 340HP and 455 lb ft of torque. If a guy were to opt for a 2000-2002 Cummins, approx the same specs, does a Diesel pull any easier. Just a thought.
I realize they tow at a much lower RPM.
Thanks. Just curious.
I would include the '03/'04 HPCR 305/555 HO Cummins in your looking. Cummins made it just those two years. Its a lot quieter and has much more towing power than the '00-'02 models that put out 235/460 for the auto and 245/505 for the NV5600 tranny. You also get the much improved 48RE auto tranny with the HO.
I had a '01 2500 Dodge/Cummins 235/460 47RE tranny 3.54 that was noisey enough to kill normal brain cells. Plus the 3.54 gears with the 47RE was rated at 9800 lbs tow capacity. It was a sick puppy in OD but ran good in drive
I have a '03 305/555 HO with the NV5600 3.73 axle. I pull a my 11200 lb 5er and a 10k bumper pull and a 14k GN flatdeck and a 16k 36' triaxle GN stock trailer.
The stock trailer is joint owned with a neighbor who pulls it with a '04 2500 chevy 8.1/Allison. At a full 16k load on the triaxle trailer he can out accelerate me for the first couple of blocks but after that the Cummins slowly leaves him behind.
I've had the Cummins way up in the 2600-2700 rpm range a couple of times but all it did was make more racket. I keep the rpms in the 2200-2400 range pulling the 16k triaxle up any grades at legal speeds or my 11200 lb 5er up mountain passes like Monarch or Parleys canyon I-80 east out of Salt Lake or Eisenhower tunnel grade in the 2300-2400 rpm range at normal speeds.
