Frequently Asked Questions
How do I check if my truck can tow my trailer?
Loaded trailer weight must be ≤ tow rating, ≤ hitch class rating, and trailer + truck combined ≤ GCWR. A 10,000 lb trailer needs at least a Class IV hitch (10,000 lb) and a tow vehicle rated for it with margin.
What is tongue weight and how do I size it?
Tongue weight = 10–15% of trailer weight for bumper-pull, 15–25% for fifth-wheel/gooseneck. A 7,000 lb travel trailer wants 700–1,050 lb on the tongue - measure with a tongue scale, not the spec sheet.
What does GVWR vs GCWR mean?
GVWR = max loaded weight of one vehicle. GCWR = max combined weight of vehicle + trailer. Towing puts the truck near both limits; a 7,000 lb truck (GVWR 7,500) pulling 10,000 lb needs GCWR ≥ 17,500 lb.
Why does payload often limit towing first?
Tongue weight + passengers + cargo all count against truck payload. A "10,000 lb tow rating" pickup with 1,500 lb payload runs out of payload at a 10,000 × 0.13 = 1,300 lb tongue plus 4 adults - long before the tow rating bites.
