So, went to Idaho for New Year's, drove from Boise to Seattle (even had to pop it into 4wd once). 483 miles, 31 gallons of fuel with the defroster (A/C) going the entire way (3 large dogs put a lot of moisture in the air), on a motor with 230,000 miles. Tell me again why people hate the 6.2/6.5 so much? I didn't stop for fuel and still could have gone at least a 100 more miles before it was in the red. And before the "it's slow" hate. Left at 9 am, got to Seattle at 5 (with a 1 1/2 hour traffic jam on Snoqualmie).... 70-80 mph the entire way, if the dogs and I had stronger bladders, we would have been faster - but alas, 2 stops for poo were required.
At the risk of people finally realizing the US Armed forces weren't stupid with them in their Humvees and therefore raising the price on them.... they're a damn good motor. Not just that but the turbo from the 5.7 Cummins is a nice upgrade. You won't win any races but I paid $300 for my diesel Suburban... tell me about how much you spent for your 200,000 mile Dodge.... For those who have done the drive, I held speed limit in all but a couple moments in the Blues and once in the hill climb out of Pendleton.
and I'm not bringing this up but for this sole reason. Overlanding has always been about the path less traveled. If you want to get into this amazing adventure but do so without spending huge sums (e.g. my wife wants a D110, projects start at 25,000 usd) look at Suburbans. They're cheap to buy, build, maintain and drive. They're reliable, they have huge space inside, and they even get remarkably good mpg.
