The Whitefeather Sprinter 4x4 conversion does provide a more capable 4x4 system but you are still limited by tire size if you want to go rock crawling and to get more clearance. Bigger tires are easier to do on an Econoline or Chevy van 4x4 conversion. All depends on how you are going to use it.

I agree. I have had this conversation so many times with people that I donít even bother anymore. Duallies are not as good as single wheels when off roading or for traction, period, for a myriad of reasons. Seems people wonít believe it because they own a dually vehicle and arenít buying into reality.

Default Whitefeather

There is a thread titled Whitefeather 4x4 Sprinter vs Mercedes Factory 4x4 on SportsmobileForum with some owner feedback on Whitefeather conversions. Interesting feedback on the improved clearance and locker capabilities but also cautionary about Whitefeather's quality control and customer support issues. Definitely worth a read if you're considering Whitefeather.

BTW, Agile Offroad apparently now has a Sprinter 4x4 suspension upgrade system available for improved articulation and ground clearance. Looks like Agile is steering clear of lockers and messing around with Mercedes differential and stability control systems for now. Perhaps wise restraint given the Whitefeather issues experienced by TNeuer.

Doug Chase certainly has a nice rig, but I'm an older female so he lost me at, "We didnít feel we needed a bathroom in the van."

Default Sprinter Conversion

BBQ - I have talked to Whitefeather and like every up-fitter I have spoken to so far, they were very good about explaining their design and process. It is the most expensive 4 x 4 conversion I have looked into so far, about double what Quiggly and Quadvan charge for their Ford Transit conversions.

There is a thread on the Sportsmobile Forums, "Whitefeather 4x4 Sprinter vs Mercedes Factory 4x4".

Hi Skutumpah,
I haven't tested the 4x4 capabilities but I can tell you that the system is really a push button AWD system with a low range transfer case. It has open differentials and uses antilock brakes to control wheel spin. It's a fantastic system to drive on snow covered roads. Like a big Subaru, but I wouldn't want to take it "off road."
The worst thing about it is it's like a part time AWD system. You have to stop to engage the system. Before I knew it wasn't really a part time 4x4 I tried to stop on the shoulder to engage the AWD system when I hit snow and stop to disengage it when the snow was over. After three mountain passes I left it engaged and it worked perfect! If I knew it was going to be a system like this I wouldn't have ordered the hi/lo range 4x4. I think the hi range is shift on the fly.
I'm thinking to sell the thing because of the diesel engine. I think I would have less problems with the FWD gas Promaster.

The 4x4 system is "stupid", odd, strange, unusual, odd, unusual...
Only a German engineer would think it is a perfectly normal operation.

The point is that I never wanted a 4x4 van but the wife/boss wouldn't let me trade in her SUV without getting a 4x4. You know that it snows like once a year here in Seattle and she doesn't want to get stuck.
