Bought diesel 2500 extended work van. Have 4k now. Build quality is great. Seating is good. Controls well placed. Dash ugly. Have '04 Ford van and Chevy drives way better. Ford constantly wanders Chevy drives straight. 62k on Ford with no repairs, hope Chevy does as well. Disappointed with Diesel MPG. Get 16MPG combined, but it is new and it is winter. Ford gets 12MPG with gas. Diesel VERY smooth and quiet. Big improvements in Diesels lately. Do not notice towing 14'box trailer with diesel. Has right porportions for extended, unlike Ford. So far so good.
Diesel gets 20 mpg or 16 mpg with 8-10,000 trailer and when in a hurry I've done 80 with a full load and pulls like it's not even there. It still drives like a cargo van. High center of gravity effects cornering. Can ride rough without a load.
