I have some questions regarding Volvos. Also, lets keep this a Volvo thread only please. I notice their gauge package is limited to 12 gauges with the optional tranny temps located by the switches for 5th wheel slide, etc.. Is their any way to add more gauges? Also, what are the weights for the VNL670 and VNL780 models. Finally, does anyone have experience with the new D13 engine.
