Just got back from a 10 day trip through Oregon, California & Arizona with the Transit. A little over 3200 miles, mix of freeways, back roads and off road. Lovin' this van!!! Smooth and comfortable, easy to drive, lots of room to move around inside.
The purpose of the trip (aside from family time and taking a small break from the non-stop work around here) was to test the driveability of the van with the lift, gearing change, larger tires. I honestly like the van a lot better now vs. stock. Feels very stable at speed and the ride is very good. Drives and handles more like a small SUV than a large van. Fully loaded with the interior and our stuff we were 7550lbs. Not heavy but you could feel the weight in the van. The Ecoboost did awesome, never felt like it was working hard and always had more go ready when I needed it. Fuel mileage was 15-ish... didn't pay much attention to it.
Off road experience was good. You can get a lot of places even with the weak factory LSD. I was really interested in getting it out in the dirt and the experience pretty much confirmed a lot of what I was already thinking of doing to make a better 4x4 conversion than what's out there. There are some weak points in the stock suspension and a few areas need to be beefed up a bit for any serious off road capability. I'm really excited to get back to the CAD workstation to work out the last few details of the 4x4 parts!
