Questions & Answers
Common Questions
How much can I actually tow with my 2015 Ram 1500 Lone Star?
+
The 2015 Ram 1500 Lone Star is rated at 8,560 lbs maximum — but the real-world best practice is the 80% rule: target 6,848 lbs as your practical limit. This gives you margin for hills, headwinds, braking distance, and real-world load variance. More critically, check your payload first — the door sticker tells you your specific truck's limit, and payload may be your actual binding constraint.
What about payload — how much stuff can I put in the truck?
+
You have 1,650 lbs of payload capacity — that's everything going IN the truck: passengers (~150 lbs each), camping gear, coolers, and critically the tongue weight from your trailer. For bumper pull trailers, tongue weight is typically 10–15% of the trailer's loaded weight. It fills up faster than most people expect, especially on longer trips.
What kind of hitch do I need?
+
For the 2015 Ram 1500 Lone Star, you need a Class III receiver hitch rated for 8,560 lbs. Don't skimp here — the hitch is the critical link between truck and trailer. For fifth wheel towing, you'll need a dedicated kingpin-style fifth wheel hitch mounted in the truck bed.
What types of RVs will work with my truck?
+
With your 6,848 lb safe towing capacity, you're looking at most travel trailers and slide-in campers. The compatibility chart above shows what percentage of each RV class in our database you can handle. Use the Tow Calculator to check a specific RV including gear, water, and passengers.
What does GVWR mean and why should I care?
+
GVWR is Gross Vehicle Weight Rating — the maximum your truck can weigh when fully loaded with people, gear, and fuel. Your truck's GVWR is 6,800 lbs. Exceed it and you're over-stressing brakes, suspension, and tires. This is different from towing capacity — it's about what the truck itself can carry.
