The Lone Star is a Texas-exclusive trim (similar to the Big Horn in other states) and it's got some fun and interesting features: IT'S THE "TEXAS EDITION" The Lone Star trim is a special edition made just for Texas buyers. It includes unique badging and upgraded interior touches like a leather-wrapped steering wheel and exclusive cloth seats with the Lone Star logo. BIG POWER BIG CHOICES Buyers could get this truck with three powerhouse engines: -5.7L HEMI V8 (383 hp 400 lb-ft) -6.4L HEMI V8 (410 hp 429 lb-ft) - Best for raw power -6.7L Cummins Turbo Diesel I6 (370 hp up to 8-- lb-ft of torque) - Best for towing The Cummins diesel option gives it legendary durability and insane pulling power. TOWS ALMOST ANYTHING With the Cummins diesel and the right towing package the 2015 Ram 2500 Lone Star can pull up to 17970 lbs making it perfect for big trailers boats or heavy equipment. THE "RamBox" OPTION IS SUPER HANDY Some models came with RamBox cargo management which are built-in waterproof storage compartments on the sides of the truck bed-great for tools fishing gear or even as ice chest for tailgating. TEXAS FLAIR INSIDE AND OUT The Lone Star edition had chrome bumpers grille and door handles plus an upgraded interior with optional woodgrain accents and premium cloth seating - way more stylish than a standard work truck. SURPRISINGLY SMOOTH RIDE FOR A HEAVY-DUTY TRUCK The rear suspension uses a five-link coil spring system instead of traditional leaf springs giving it a more comfortable ride than other HD trucks in its class. It also has an optional rear air suspension which helps level heavy loads. BIG ENOUGH FOR THE WHOLE CREW The Crew Cab offers huge rear legroom making it one of the best heavy-duty trucks for passengers. Some models even came with heated seats and an 8.4-inch Uconnect touchscreen making it feel more like a luxury truck inside.
