You mentioned you were going to give a review of road manners of the old and new drive trains on the trip home from outdoor East. Have you posted that somewhere?
I have not, so here it goes!
The primary difference between the V8 and the diesel platforms, as it relates to road travel, would be the top speed and pick-up. While the diesel units are good in both of these areas, the V8 chassis is definitely an upgrade. My trip from Chicago to Bend a few weeks ago was certainly an experience, including an almost two day road closure in Wyoming. A road closure that I thought I could get around at first with a detour down 230 out of Laramie south into Colorado and then back up to Rawlins....(MISTAKE!) 230/130 during a snow/wind storm was challenging (to say the least)
Luckily, I was in one of the most capable 4x4 vehicles in our industry..(IMHO) and almost 4 hrs later I was back on I-80....still closed!
But, I am getting sidetracked...
The majority of the drive was uneventful and I was able to run consistently at speeds in excess of 80 mph! Mostly I kept the cruise set around 78 mph though. It was nice to be running 70 mph and know you had a "kick" left for passing. She pulled up grades with ease and the custom EarthCruiser reprogrammed Allison just seemed to know when to shift to keep a nice steady "pull" uphill.
The truck handled like a dream even though the demo V8 didn't even have our new hydraulic steering assist installed yet.
I was concerned that the additional tire size (37" Toyo's up from 35") might give the front end a more "squishy" feeling, but I can say that I was very impressed at how stable and responsive the front end felt.
Braking was fantastic, the new V8 has 4 wheel disc brakes and they perform wonderfully. In fact, the reason the EC was in the Midwest to begin with is that we had her at a national brake testing facility in Ohio prior to the Chicago Boat Show. Brake testing is something we take very seriously, as you would expect, and our new disc system passed with flying colors. And after a couple of thousand miles behind the wheel in some pretty "hilly" conditions, I can concur that this system is well equipped to answer the call.
