The Towing Vehicle Recommendation Tool matches your trailer's fully loaded weight (not empty weight) against a vehicle's real tow rating, and applies a safety buffer so you're not shopping right at the vehicle's max-rated limit. A common rule of thumb: don't plan to regularly tow more than 80% of a vehicle's advertised max tow rating. Tongue weight should generally run 10-15% of trailer weight — get that wrong and even a properly rated tow vehicle can handle poorly.
At a glance
| Trailer type | Typical loaded weight |
|---|---|
| Small utility/boat trailer | 1,500-3,500 lbs |
| Travel trailer (mid-size) | 5,000-8,000 lbs |
| Large travel trailer/toy hauler | 8,000-12,000+ lbs |
| Car/equipment trailer | 3,000-10,000+ lbs depending on cargo |
Why the brochure max-tow number is a starting point, not a target
Manufacturers advertise max tow ratings under close-to-ideal conditions: a specific trim, minimal passengers and cargo, and often a base configuration that isn't what most buyers actually order. The Towing Vehicle Recommendation Tool treats the advertised number as a ceiling to stay well under, not a target to aim for, because every passenger, cooler, and accessory you add eats into that headroom.
The three numbers that actually matter
Trailer loaded weight (GTW)
Gross Trailer Weight is the trailer fully loaded with everything you'll actually bring — water, gear, propane tanks, the works — not the empty weight from the trailer's spec sheet. This is consistently the number people underestimate the most; a travel trailer's "dry weight" can be 1,000-2,000 lbs lighter than how it actually tows loaded for a trip.
Tongue weight
Tongue weight (the downward force the trailer puts on the hitch) should generally be 10-15% of GTW for a conventional trailer. Too little tongue weight causes dangerous trailer sway; too much overloads the rear axle and headlights aim upward. Tongue weight also counts against the tow vehicle's payload capacity, which is a common oversight.
Hitch class and receiver rating
Even a properly tow-rated vehicle needs the right hitch class installed — Class III and IV hitches handle most mid-size trailers, while heavier trailers need Class V or a gooseneck/fifth-wheel setup. The tool flags the minimum hitch class needed for your trailer weight.
Worked example
A buyer wants to tow a travel trailer with a loaded weight of 7,200 lbs and an estimated tongue weight around 850 lbs. Applying an 80% buffer, the tool looks for tow vehicles rated at roughly 9,000 lbs or more, and checks that the vehicle's payload rating comfortably covers the 850 lb tongue weight plus passengers and gear — ruling out vehicles that technically clear the tow rating but would be overloaded on payload once tongue weight and cargo are added.
A vehicle can have plenty of tow capacity left but still be over its payload limit once tongue weight, passengers and cargo are added. Check both numbers, and check the specific trim and options package — tow ratings vary meaningfully between trims of the same model.
Common mistakes when shopping for a tow vehicle
- Using a trailer's empty/dry weight instead of realistic loaded weight when matching to a tow rating
- Shopping right at a vehicle's max-rated tow capacity with no buffer for passengers, gear or hills
- Forgetting that tongue weight counts against payload, not just against the tow rating
- Assuming all trims of a model share the same tow rating — engine, axle ratio and tow package options all change it
