Above 100,000 miles: Ford/Chevy/Dodge vans?

1999 Chevy 2500 Express, extended van with the larger v-8 had the tranny go south at 140,000. It hauled a lot of tools, materials and construction debris over its life, and occasionally pulled a cargo trailer with motorcycles in it to Florida and back. It was 13 years old when I traded it in on a new, 2012 2500 extended wheelbase, just like the '99, but with a smaller v-8 and a 6-speed tranny. Other than a fuel pump, and the dead tranny, I had zero issues with the '99. I opted to buy another, rather than go with a Ford extended box that uses the same wheelbase with a longer rear overhang. Besides a better towing capacity, the Chevy seems to have a roomier passenger-side foot area and a smoother ride, as well. I never considered a Dodge.
