Also for 25k, that gets me 2/3 of a newer van in stock form. Hard to let go of something nearly perfect setup for us and mostly dialed in build for a minor amount of driveability improvement and a complete build all over again. All your comments definitely help for perspective.
I love the weldtec stuff. Visited Jeremy last year on a road trip. He's a good guy and knows a ton of stuff. Pop tops definitely more enticing that 4wd right now. I don't mind the chains in the snow for what small amount of snow driving it gets.
And yes, I saw the Ecoboost tuned might get 18 if it's unloaded and light. Maybe. The 2.8l Dmax gets some decent mpg but I can't imagine it being very safe or fun to drive with that little power on a big built van.
