Thanks for posting this.
Before someone writes (correctly) that you could, for about the same investment, get a 2015 Mercedes/Freightliner 4x4 and add the farkles, it's worth pointing out that the WhiteFeather conversions are a good deal more off-road oriented. If you look at the components listed in the Craigslist ad, you'll see a lot of reasonably serious stuff. Their conversions are conceptually similar to what U-Joint and others do for E-Series vans, and they're capable of more serious trail work than could be handled with the factory 4x4.
Not surprisingly--and as with pretty much all trail-modded vehicles--the WhiteFeather conversion has to give away some of the stock vehicle's good on-pavement manners. The Sprinter 4x4 is a really good addition to the model line, but as you can tell from the videos on the web (like
https://www.youtube.com/watch?v=WgN5az6UWu0), the factory model is not designed to be a hard core trail rig. It'll be great for getting through moderate snow and for expanding the Sprinter's range to a wider variety of dirt roads and less ideal weather conditions. On balance, the off-road-oriented WhiteFeather conversion will do much better on a trail, but you won't like it nearly as well as the factory truck for an on-pavement driver.
So, as with so much discussed herein, you get to pay big bucks for the right to compromise.
