Myself, I prefer gas engines -- but was wondering about the power for a large, heavy van and a V-6. I'm generally a GM guy, and had a Safari with the V-6 3.6 AWD, and it was bulletproof for 190,000 miles, then gave it to my teen son who drove it for a few years. But was curious about up-hill power because we drive the Rockies a lot. Altho we did two a dirt bike trailer with it for a lot of miles too, with no issues.
I don't see any AWD options except the REVEL 4x4 ... although that looks like a great Van, except the price tag.
