💡 Where to find these numbers: Check the sticker on your driver's door jamb, your owner's manual, or search "[Year] [Make] [Model] GCWR". Selecting a trim above auto-fills these for you.

Truck Load — what's inside your cab and bed

Passengers + Driver (lbs)

Cargo in Bed / Cab (lbs)

Fuel Weight (lbs)

Hitch + Accessories (lbs)

⚠️ Most people forget this step. Passengers, gear, and a full fuel tank can easily subtract 600–800 lbs from your available capacity. This is the #1 cause of overloaded tow setups.

Your Trailer

Trailer Weight Fully loaded (lbs)

Tongue Weight Typically 10–15% of trailer (lbs)

📌 Use loaded weight, not dry weight. The "dry weight" on a trailer spec sheet doesn't include your gear, water, food, or people inside. Loaded weight is often 20–40% higher than dry.
