2015 Ram 3500hd 6.7 4x4 w/ Aisin, 8 inch on 24x14

Hey everyone! I've seen a lot of folks asking about the 2015 Ram 3500, especially the 6.7L Cummins with the Aisin transmission, so I wanted to share my personal take after owning mine for a while. If you're looking for a heavy-duty truck that can tackle just about anything, this one should definitely be on your radar. Why I Chose the 2015 Ram 3500 HD When I was in the market for a new truck, I needed something reliable and powerful for both work and play – think heavy fifth-wheel camper weekends and hauling equipment. The 2015 Ram 3500 HD, particularly with the legendary 6.7L Cummins diesel and robust Aisin automatic transmission, kept coming up. This combination promised serious torque and durability, exactly what I needed. Engine & Transmission: A True Powerhouse The 6.7L Cummins engine is phenomenal. Power delivery is incredibly smooth, and the torque is on another level – it pulls my heavy trailer effortlessly, even up steep grades. The Aisin transmission pairs perfectly, shifting crisply and confidently, never hunting for gears. It handles heavy loads without breaking a sweat, giving me peace of mind when loaded down. This combo is absolutely bulletproof. The Lift & Wheels: Performance Meets Aesthetics My truck isn't stock; it has an 8-inch lift kit riding on 24x14 wheels. Many ask how this affects the ride. I love the stance and look. The lift gives it a commanding presence. While the ride is firmer than stock, it's surprisingly comfortable for a heavy-duty rig. You feel the road more, but it’s not harsh. The larger tires and wheels do slightly impact fuel economy and parking, but the aesthetic and added ground clearance are worth it to me. Quality lift and proper alignment are key for good handling. Towing & Hauling Capabilities This is where the 2015 Ram 3500 truly shines. The Cummins and Aisin combo provides incredible towing capacity. I've towed everything from heavy equipment to my fifth-wheel RV, and it handles it all with confidence. The integrated trailer brake controller works flawlessly, and the exhaust brake is a game-changer, especially on downhill stretches, saving your brakes and providing incredible control. It makes long hauls less stressful and much safer. Daily Driving & Comfort For a truck this size, it’s pretty manageable for daily driving. It’s not as nimble as a half-ton, but steering is responsive, and you get used to its dimensions. The interior is spacious, and even in my older model, the seats are comfortable for long trips. Visibility is excellent. Fuel economy, as expected with a lifted diesel dually, isn't stellar, but it’s acceptable for the power and capability you get. Maintenance & Reliability My 2015 Ram 3500 has been incredibly reliable. I stick to the recommended maintenance schedule, especially fluid changes for the engine and transmission, and it has served me well. Diesel maintenance can be a bit more expensive than gas, but it’s an investment in longevity. I haven't had any major issues, a testament to the build quality. Pros: Unmatched towing/hauling power (6.7L Cummins). Extremely durable and smooth Aisin transmission. Commanding presence and 4x4 capability. Spacious, comfortable interior. Excellent reliability with proper maintenance. Cons: Fuel economy isn't great (especially with mods). Large size can be challenging in tight spots. Higher diesel maintenance costs. Firm ride, particularly with a lift. Final Thoughts: Is It Still Worth It? Absolutely! For anyone needing a serious workhorse or robust tow vehicle, the 2015 Ram 3500 HD with the 6.7L Cummins and Aisin is still an outstanding choice. It's built to last, incredibly capable, and offers a driving experience hard to beat in the heavy-duty segment. Even with a few years on it, mine still feels strong and dependable. If you find one in good condition, I highly recommend considering it. It's a truck that truly earns its keep!
