Questions & Answers
Common Questions
How much can I actually tow with my 2010 Dodge Ram 3500 SLT?
+
The 2010 Dodge Ram 3500 SLT is rated at 17,100 lbs maximum — but the real-world best practice is the 80% rule: target 13,680 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 4,180 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 2010 Dodge Ram 3500 SLT, you need a Class V receiver hitch rated for 17,100 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 13,680 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 11,500 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.
