I'd do it! Then again, I towed at 15-16K lbs with my old GM 6.5td that had a whopping 12500 GCWR due to having the NV4500 vs the POS 6l80e auto trans! ANy way......If as "dad" mentions, the new version have a higher number of gears in the trans, a turbo etc......you might find you are faster, better towing etc than your current 6 cylinder. With a turbo, you're ready for higher elevations vs a non forced induction motor, that loses 2-3% of it HP per 1000' above sea level you are. Many turbo'd rigs give you se level HP to 10K'!
Of course, this is a person thinking of trading in his 250HP 350 V8 4 spd auto/4.10 gears for a 300HP 4.3 V6 with a lower and taller geared 6 sp auto and 3.42 or 3.23 gears........I'd give the 300 pony rig a better chance of pulling a given hill faster than the 255HP rig. Both have about the same torque!
