Frequently Asked Questions

What is tongue weight and why does it matter?+
Tongue weight = downward force trailer exerts on hitch. Should be 10–15% of trailer weight (travel trailers) or 15–25% (5th wheels). Too much: sagging rear, steering issues. Too little: trailer sway.
What's the difference between towing and payload?+
Payload = what you carry IN the truck (cargo + passengers + tongue weight). Towing = what you pull BEHIND. Tongue weight counts against payload—a 500 lb tongue reduces payload by 500 lbs.
How much can a half-ton truck tow?+
Modern half-tons (F-150, Silverado 1500, Ram 1500): 5,000–13,000 lbs depending on engine, axle ratio, and tow package. Always check the door jamb sticker and towing guide—advertised max requires specific configuration.
Do I need a weight distribution hitch?+
If trailer >50% of tow capacity or tongue weight >500 lbs, yes. A WD hitch distributes tongue weight across all axles, improving steering, braking, and ride height. Required for most travel trailers.
What affects towing capacity?+
Engine power, transmission cooling, axle ratio (higher = more tow), frame strength, hitch rating, brake controller, tire load rating. Tow packages add transmission coolers, upgraded suspension, and higher axle ratios.
