Does anyone know what frame the 2500 Van's (Savanna/Express) use? Is it like a "light duty" frame like the 2500 Suburban and 1500HD trucks have? Or is it a true 2500HD frame like the 2500HD/3500 trucks?
The 2500 vans have a 8600 GVWR, and so does the 2500 Burban, so thats why I was wondering...
As far as the nav unit in a van, I dont see why it would not work...you will need to buy an external aftermarket amplifier and a PAC AOEM-GM24 adapter to make the aftermarket amp work. You will also need to buy a NON-lux nav unit. Finally, you may need to wire up a Class II data wire to the radio harness...im not sure if the base model radios in the vans include the Class II wire in the harness... But otherwise it should work.
Sorry, I didn't pay attention to the fact you were wondering about 2500 vans, not 3500's (I didn't think that the Duramax would be offered in the 2500's). I did notice that the 4.8's have 225 tires standard, and the Duramax comes with 245's (probably just for the extra engine weight).
Thanks for the info about a nav system. Thats is about what I thought, and probably wouldn't put that much money into a work truck.
