Lot's of interesting opinions. Thanks for everyone that took the time to explain their decision making. Honestly, for me, fuel mileage/costs are not a deciding factor. This is a fun time rig, so if I want to go someplace, I'm just going no matter what. I have a 2015 GMC Sierra with a Duramax in it. I love the fact that I can just step on the gas and climb any hill with no issues. Das Bus weighs about 12k pounds loaded up, so at 10,000 feet it REALLY struggles up hills. Like 25mph up the big pass by my house. A van will obviously weigh much less, but it's still not an easy climb. That being said, my truck runs DEF, so that basically eliminates me ever worrying about the rolling coal issue.
