Has anyone seen this aftermarket highroof before (Sprinter)?

For future reference, I received an email back from the company and it appears that the conversion for a 2001-2006 Sprinter starts at around $4200.

It may be worth it considering that the low-roof model is often times many thousands less than a Sprinter high roof, and with this conversion you get even more headroom.

That's an excellent point. The high roof T1N Sprinters aren't all that tall for lanky Americans. With just the factory load floor, a six-footer will brush the ceiling ribs. Of course, the stock high roof is already tall at about 9 feet, so with that conversion, occasional height issues will be more common.

FWIW, another way to get a giant interior height with a T1N is to get the James Cook/Airstream Sprinter Westfalia conversion. It's a zany layout with even zanier looks, but it can't be beat for interior volume on a 140 inch wb Sprinter.

I have a hard time understanding how a forward facing V can be good for aerodynamics. I know the air dams up and creates a cushion that some air moves around, but still, it is a forward facing V.

Good thing it has the rear lined with those little aero devices! :)

Pretty sure those are vortex generators. If I understand the physics correctly, he is attempting to keep the airflow moving off the broad surfaces in a straighter line rather than "tumbling" off the sides behind the vehicle creating additional drag. I think there is some evidence that it can be effective depending on the vehicle, similar to the areo mods, often a kind of fold out v shape, on the rear of the long haul semis these days. I'm sure someone will be along who can better detail their use.

interesting, I had noticed them but never realized this.

Also, I have had a couple email exchanges with the company and they are looking for 2007+ model to do their first install (and give a discount).

I missed this one for a month, but if anyone cares, the vortex generators on the Sprinter are Airtabs (http://www.airtab.com). I fooled around with them trying to get rid of a wind howl under the cabin nose extension on the XV-JP. Pictures and information here:
