7-8 seat tow Vehicle?

I am not sure why you do not want a van. I just moved to a Chevrolet Express. It was a 2014, used as a rental. It was incorrectly noted that they came standard with the 6.0. It does come with a 4.8 V8. I bought mine Certified Pre Owned, so I have a 12 month/12k mile bumper to bumper warranty. I paid $175 to have a RV place wire the van for 7-way plug. The regular length parks better than the Silverado did, and is easier backing my trailer. Not towing, I am getting 17-18 mpg on highway.
