Heavy Duty Truck FAQs

What is the difference between a 2500 and 3500 truck?

The main difference is payload and towing capacity. A 2500 (3/4 Ton) is great for heavy towing while maintaining a smoother daily ride. A 3500 (1 Ton) has a stiffer suspension built for maximum payload and heavier fifth-wheel trailers. 3500s are also available as a "dually" (dual rear wheels) for ultimate stability.

Do you have diesel dually trucks in stock?

Yes. We specialize in diesel performance and keep a deep inventory of RAM 3500, Chevy Silverado 3500, and GMC Sierra 3500 dually trucks equipped with Cummins and Duramax engines.

Can I customize my Heavy Duty truck before I buy it?

Absolutely. Our accessories department can add lift kits, heavy-duty bumpers, winches, bed liners, and upgraded lighting to your truck before you take delivery.

Do you deliver heavy duty trucks out of state?

Yes. If you can't make the trip to Kellogg, we can arrange shipping for your new heavy-duty truck directly to your home or business anywhere in the US.
