The 1430 is the Canadian model number for the 1 Ton. The GMC version would be a 9430 such as my own 1 Ton. If it has single wheels on the rear, the GVW will be somewhere around 5800 lbs but with the duals, it goes up to 8000 lbs. The wheel base should be 137". I have the complete chart for the model numbers if you want them.
