The Dynamax DX3 expands on power, prestige, and precision. It turns heads with its impeccable paint and eye-catching curb appeal. A look under the DX3â€™s hood reveals the CumminsÂ® 8.9L 350 HP engine and the AllisonÂ® 3200 TRV automatic transmission, resulting in remarkable torque (1,000 lb.-ft.) and towing capacity (20,000 lbs.). All this power and performance is perfectly matched with a living space that exceeds expectations. Find your own Dynamax DX3 for sale here at RVT.com.
