My van is a Waldock Conversion. They did a very nice job, except the add-on rear a/c leaked and needed repair under their warranty, which they approved the dealer to complete without trouble. I will describe my van here as a Ford e150 and not include the conversion aspect (though there is nothing other than stated I have ever had to deal with regarding the conversion). It has been a wonderful highway rig. Smooth and quiet. Suspension is a little soft, but that is also what makes it so smooth riding. Only issue taken care of early was a water pump gasket under warranty. No other issues. Belt, brakes, tires, oil, only up-keep. Low 80,000 miles, but no issues. It's been great!
Nice limited slip rear end for snow traction. Michilin LTX's make for good snow traction and quiet ride.
