2024 Chevy Silverado 3500hd Dual Fuel. Since 2 boxes under the bed ahead of axle rear axle (rh and lh) will be enough storage for what i need on the farm i am thinking about adding an auxiliary fuel. Does it make any difference which tank gets filled first?

From what i have found out, it uses a transfer. The 2024 chevy silverado 3500 hd handles highway hauling like an even bigger truck, despite its lack of groundbreaking technology.
