First time Rock Crawling and the 2GR-FKS

Ok guys! By this time we were a couple hours into the trail and I had a firm opinion on the new 3.5-liter engine and Rock Crawling.

I am extremely pleased to report that this engine is the best, low-RPM lugging engine I've ever experienced. I can get the truck moving so slow and steady at approximately 250 RPM and it not only won't stall but it doesn't even shake -- it is entirely smooth at sub-400 RPM engine speeds for as long as needed. I was most impressed by this. All I have to do is take a slightly steeper line and not give any gas and let the weight of the truck load the engine down for a continuous & steady low engine speed. This is the control I've been preaching about when you install a Marlin Crawler.

For comparison my Hilux's 2.7-liter 3RZ-FE can lug down to and sustain about 350-400 RPM before it gives up the ghost, but at this RPM it is shaking and rattling quite badly. The new 3.5 V6 is extremely impressive. A 6-cyl engine has a power stroke 30 fewer degrees of crankshaft rotation compared to a 4-cyl, but no doubt progress in modern engine's Noise Vibration Harshness (Wiki:NVH) is really shining here with the modern 2GR.
