JFloFoto, did you ever get the Nations dual alternator kit installed?
I did. Dennis at Linden Engineering installed it for me.
The details: Since I ordered the van with an aux alt bracket option, it was a simple bolt on. The Nations aux alt kit came with a bracket which was not necessary. I returned the bracket to Nations for a refund. Nations also suggested a longer MB belt since the original would need to be replaced, so I bought one and a back-up just in case. Dennis used the longer belt in the install. He mounted the Balmar charge regulator on the air box so it is accessible in case any programming adjustments need to be done in the future. Cost was a couple of hours of labor. I have not hooked it up to house batteries yet.
He also dropped my tank and installed a extra fuel tap for my D2. I needed an extra since my van came with the heater booster which took the auxilliary tap.
Finally, I wanted him to enable my cornering lights. He wasn't able to do it without the proper software, but told me that he ordered it and should be able to do it soon. He's had a lot of other requests so decided to go ahead and get the program.
