Questions & Answers
Common Questions
How much can I actually tow with my 2015 Ram 2500 Laramie Longhorn?
+
The 2015 Ram 2500 Laramie Longhorn is rated at 15,190 lbs maximum — but the real-world best practice is the 80% rule: target 12,152 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 1,950 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 2500 Laramie Longhorn, you need a Class V receiver hitch rated for 15,190 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 12,152 lb safe towing capacity, you're looking at a great selection of travel trailers, toy haulers, and many fifth wheels. 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 9,000 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.
