I had one with the 5.7 and it no way tows better than the Tundra not even close in my experience .
The tranny in Jeep GC was not the greatest , had 2 replaced and it barely towed up to it's rating , so I honestly can't see you saying it pulled better up a grade than the Tundra under any circumstances .

By the way 15% and 7% are huge numbers considering they both are 5.7 's .

I don't believe I ever said or implied that the Jeep towed better or even close. What I am saying is that if the gear ratios were the same, the power differance wouldn't be that great....torque pulls, HP holds you there. We can agree to disagree....7% torque differance is just not that great....what about 12 to 17 ft/lbs or so of actual differance. To put the torque differance into perspective...the differance is about the same as 2 21" lawnmower engines.

You're correct in that the Jeep wasn't designed for towing but the 5.7 was. There are a heck of a lot more HEMIS towing heavy loads then there are Tundras. The Ram HEMI both 1/2 ton and 3/4 ton with 4.11 or 4.33 rear gears are great towing trucks. The Tundra with a newer engine design has the power advantage this year. Next year, who knows.

I sure would like to find Dyno curves for the Tundra. I keep hearing the claims about super broad curves but I haven't seen the data.
