I just returned from Austin with a stop at Van Compass along the way.
Do yourself a favor, lay down under your Sprinter and look, then you will see the wisdom in installing the package. I know I'm glad I did. And FYI, there are no conflicts with this and the Aluminess front winch bumper.
Mark and Rob are great guys and we thoroughly enjoyed meeting them and doing business with them. We walked down the street and had breakfast while they did the install, no issues and easy enough to do yourself, but if you are passing by....
One thing not mentioned above is the added protection if you install the 2nd alternator. It is low, maybe 17" above ground on the 4x4, and it is exposed. In snow country I would see the engine skid plate as required, both for 2wd and 4wd. Mark and Rob told me of one customer who came in for the protection AFTER snow packed in and killed the alternator. My van doesn't have the 2nd alternator, but it does have the bracket in case I decide I want it in the future.
Here is a picture I took of my van, you can see the bracket where the 2nd alternator would be installed, just above and protected by the engine skid plate.
