GarageCalc Reading these numbers correctly
The max rating applies to one specific configuration, usually the lightest cab with the strongest engine and a factory tow package. The base rating is what the least tow-oriented configuration is certified for. Your Grand Highlander sits somewhere in that range, and the only way to know exactly where is your VIN-specific documentation.
Also remember that tongue weight (10-15 percent of the trailer) counts against payload, not the tow rating. A Grand Highlander can be inside its towing limit and over its payload limit at the same time. Our towing calculator works out the real-world numbers from your GCWR and curb weight.
Frequently asked questions
Which Toyota Grand Highlander configuration tows the most?
A gas 2.4T or Hybrid Max model: 5,000 lb. Only the efficiency-focused 2.5L hybrid is capped lower.
Can a Toyota Grand Highlander tow a travel trailer?
The strongest recent configurations are rated up to 5,000 lb. That covers many mid-size travel trailers, most boats and utility trailers, but stay well clear of the limit for large trailers. Keep the loaded trailer weight, not the empty weight, under the rating for your exact configuration.
Do I need a weight-distribution hitch?
Most manufacturers require a weight-distributing hitch above roughly 5,000 lb of trailer weight, and it noticeably improves stability well below that. Check the towing section of the owner’s manual for the exact threshold for your model year.
